Artificial Intelligence (AI) in the World of Microsystem Manufacturing

The presence of artificial intelligence (AI) has become quite significant in many applications. Most notably in big data analytics, facial recognition software, military equipment, and self-driving cars, among others.

What is AI?


AI enables machines to think. It provides the ability of the machine or software application to learn, act, and reason like human cognition. The beginning of AI goes back to the 1950s. However, recent developments in AI technology catapults the concept into new abilities and uses.

This is possible by creating sophisticated machine-learning algorithms to process huge data sets, learn from experience, and improve over time. It was in 2010 that advances in deep learning came.

That enabled the processing of a wider range of data through a certain type of machine-learning, requiring fewer data preprocessing done by human operators, and often producing more accurate results.


What is the role of AI in microsystem manufacturing?


There is a significant role of AI in the semiconductor industry due to its potential of creating huge business value. In fact, microsystem manufacturing companies investing in AI/ML are already generating value.

These are companies making notable investments in AI/ML talent, particularly in data infrastructure, technology, and other factors. They have also fully scaled up their initial use cases for that matter.

Although many are still in the pilot phase in terms of AI/ML, forecasts suggest that its application of such technology can accelerate dramatically over the next few years. If companies will take steps to scale up now, they will be able to capture the full benefits of such technologies.


How AI offers opportunities for microsystem companies


Chips intended to work with machine learning, or the neural networks called AI accelerators are expected to have a growth rate of approximately 18% per annum. This is more than 5 times the growth seen for semiconductor companies using non-AI applications. These also include areas of high growth in AI chips for the broader field of neural networks and for autonomous vehicles.

Neural networks are specialized AI algorithms working just as the human brain does. These are able to interpret sensory data and deliver patterns in huge amounts of unstructured data. Such is quite useful for facial recognition, predictive analysis, self-driving cars, and targeted marketing.

This is when microsystem manufacturing will benefit from the creation of AI accelerators and multiple inferencing chips required in the development of such AI technologies.


How semiconductor companies profit from AI technology


There are various areas of microsystem manufacturing that can benefit from the adoption of AI technology which includes but are not limited to the following.

  • High-bandwidth memory
  • High-speed interconnected hardware
  • Networking chips
  • Non-volatile memory
  • On-chip memory
  • Storage

mixed signal soc

How to Debug a Mixed Signal SOC

Chipmakers strictly implement verification and debugging in a typical analog and mixed signal SOC design. This is important for manufacturing companies to save billions of dollars effectively and efficiently.


The designs can have a huge impact on the verification cycle when they become bigger and more complex. In fact, verification engineers often face various challenges daily for the verification of modern mixed signal SOC.


What is a mixed signal SOC?


A mixed signal SOC is the integration of both analog and digital functionality within the same chip. The key in the verification process of the analog and mixed signal design is the interaction between them.


There can be various components within a semiconductor SOC at different levels of abstractions from different sources and languages. In the design process, there must be an integration of IPs at various levels without losing its overall design goals.


Thus, there should be a thorough testing of IP quality inside and outside of the SOC. Designers have a huge role during the design considering the size of SOC with multiple IPs. They must have effective debugging tools having quick and easy visualization, annotation, and navigation, among other tools to make the right decisions.


How do you debug a mixed signal SOC?


The cost of chips in the semiconductor industry is skyrocketing due to the global chip shortage, particularly in the automotive industry. The manufacture of a robust chip employs a long, iterative process that may require a lot of re-spins.


This is the main reason why it is very important to find and fix bugs as early as the development cycle than during the implementation wherein they can get a hundred times more expensive to fix.


As a result, proper verification and debugging will have fewer re-spins, faster market-to-market, lower costs, and more reliable products. But how do you debug a mixed signal SOC for that matter?


Here are steps to debug mixed signal SOC in an effective and efficient way to avoid certain issues:


  • Test bench configuration using SPICE design and Verilog-AMS model in the AMS simulation
  • Narrow down the issue in the SPICE design during the AMS simulation using the modeling approach
  • Set up the correct Connect module via the Connect Rule in the AMS simulation
  • Include the correct process corners in the SPICE simulation
  • Force/access the SPICE net from the System Verilog test bench
  • Speed up the simulation time using appropriate levels of wave dump in the SPICE simulation
  • Select the appropriate simulator with the correct speed/accuracy options for the AMS simulations
  • Use the Verilog-AMS netlist for the AMS simulations


Note that there are common issues encountered during the AMS simulation. AMS verification engineers can debug and verify mixed signal SOC using this guide.


  • Pin swapped or mismatched between analog IPs when integrated at the analog top level
  • Branch not terminated properly in a Verilog-AMS model
  • The simulation takes longer due to the large dump file size and SPICE design
  • Some domains do not show correct values because of incorrect connect module
  • Improper simulator settings leading to incorrect results
  • Mismatched digital control signals coming to the analog IPs
  • Hierarchical references in the digital test bench

ASIC card

How the ASIC Card Is Made: The Ins And Outs of Fabless Manufacturing

An application-specific integrated circuit (ASIC) is a microchip made for a particular application. In contrast to general integrated circuits, ASIC cards allow specific actions to take place inside a specific device.


ASIC is a preferred choice because it’s smaller in comparison to multiple interconnected standard products on a PC board. This variability in size allows the chip to be as large or as small as possible. This has become the trend for the shrinking of electronic equipment sizes in recent years.


What is an ASIC Card?

While the original cost of design can be high, ASICs provide a cost-effective solution. ASIC cards are in products like mobile phones and other popular consumer devices that require large production runs.


Designers can benefit from ASICs for a variety of reasons, which include the following.


  • Decrease the size of the device
  • Perform specialized functions
  • Avoid issues with supply chains
  • Make it hard for the competition to emulate products using custom chips


The use of an ASIC card enables the consolidation of multiple functions on a single chip. Thus, ASIC products need fewer electronic components and are also cheaper and easier to assemble.


What is Fabless Manufacturing?

Semiconductor companies require significant contributions in terms of capital, staff, and resources, aside from equipment, infrastructure, and storage facilities to supplement the process of manufacturing.


Thus, they have gone for a fabless model. This is a cost-effective alternative to allow them to share existing facilities of third parties that will perfectly fit their requirements. Fabless companies can focus their time, effort, and resources on developing new ideas. Because of this, they can maintain the variability in production volume, efficiency, and velocity without the pressure on resources and their staff.


Fabless manufacturing of semiconductors benefits a variety of electronics, particularly digital cameras, smartphones, and smart cars. Such companies will design and sell hardware and semiconductor chips but don’t manufacture the chips or silicon wafers they use in their products.


That is because they outsource the fabrication to manufacturing plants or foundries. Such foundries are in countries where skilled labor is abundant and cheap. This is where they keep the production costs low and return on investment high.


Products made by these fabless companies are used in many market-leading corporations today, including top companies like Apple, Dell, and Samsung, just to name a few.

Sensor ASIC

Inductive Sensing and Sensor ASIC: What It’s All About

Inductive sensors are intended to calculate the speed or position, particularly in harsh environments. Sensor ASIC can help enhance the sensor’s interface. Nevertheless, the use of this term and technique can be confusing to many engineers.

That is since inductive position and speed sensors are available in many different designs, shapes, and sizes. Accordingly, all inductive sensors would work on transformer principles and use a physical phenomenon based on alternating electrical currents.

The Technology Used in Inductive Sensing

An inductive sensor can detect ferrous metal targets even without physical contact. At the same time, it can detect non-ferrous metal targets such as aluminum, brass, and copper. The only problem with non-ferrous metal targets is that they can decrease the sensing range of the inductive sensor.

Sensing Range

  • This is the distance from the face of the sensor to the maximum distance it can detect a metal target.

Correction Factor

  •  Note that when the object is non-ferrous metal or one that doesn’t have a significant amount of iron within it, a simple correction factor is required to define the sensing distance.

Parts of Inductive Sensors

  • The main external parts of the inductive sensor include the body, face, indicator light, and cable end.

The use of sensor ASIC technology will eventually make it possible to detect changes along with the intelligent interface between the sensor and the user daily.

How an Inductive Sensor Works

Inductive sensors use a coil to generate a high-frequency magnetic field. So, if there is a metal object close to the changing magnetic field, the current will flow in the object. A new magnetic field is set up from the resulting flow of current, which opposes the original magnetic field.

Inductive sensors are non-contact and work for the detection of metal objects. These sensors use a magnetic field generated in front of the sensor. So, if you put a metal target close to the face of the sensor, it will disrupt the electromagnetic field. This will cause the output and indicator light of the sensor to turn on.

Advantages of Using an Inductive Sensor

Inductive sensors are solid-state and they don’t have any moving parts. This means that they are quite reliable because they only need replacing if they have physical damage.

On the other hand, these sensors can still work even when they get dirty. So, even if they gather dirt, grease, oil, or sawdust, it will not affect how they detect the targets.

Applications of Inductive Sensors and Sensor ASIC

Inductive sensors for automation detect parts in place at conveyor stops, at robots, and workstations. At the same time, they can detect if an air cylinder is retracted or extended. These can also detect a pallet stop or if a chain transfer is lowered or raised.

Lots of industries use ASICs to provide various solutions. Sensor ASIC is only one of the many innovations capable of enhancing the sensor interface.

Linear Microsystems in Healthcare: Ultrasound Machines and ASIC

Ultrasound machines play a major role in healthcare in a variety of ways. Traditionally, ultrasounds are display images for prenatal applications and internal medicine. The use of microsystems and application-specific integrated circuit (ASIC) technology in the development of innovative medical and healthcare solutions, like ultrasound technology, helps make this possible.

Importance of Ultrasound Technology in Healthcare

Ultrasound waveforms transmit and focus along a vector or beam. The ultrasonic energy reflects from the patient and focuses to form a picture of an object from the signal received.

The moment the beam is collected, the operation will be repeated by the ultrasound imager. Thus, collecting a series of beams that reconstruct into a two-dimensional image.

Aside from prenatal applications and internal medicine, there are newer applications for ultrasound technology which including the following:

Dental Descaling

  • The use of ultrasound technology in dental medicine is for periodontal therapy. This is in the form of ultrasound debridement. This application is more effective and efficient than manual debridement.

Shockwave Lithotripsy

  • As the name suggests, this process breaks up kidney stones and other calcium-based growths inside the body with the use of ultrasonic waves. This is quite useful to break up the stones that will not pass naturally. In fact, it is an excellent alternative to surgery.

Research also shows that high-resolution focused beams of ultrasonic energy have been used for imaging purposes in non-destructive testing and by the medical profession. This is achievable by pulsing the elements of the ultrasonic array transducer in a predetermined manner.

Role of ASIC technology in the healthcare process

ASIC technology also plays a great role in the healthcare process with implantable medical devices providing therapy for several conditions. Medically integrated circuits are in devices that are programmable to administer drugs on a more effective schedule. This will help in providing effective treatment and relief of patient’s conditions with lesser side effects.

Medical ASIC does several supporting functions for implanted medical devices, which include the following:

  • Communications
  • Sensing
  • Stimulation
  • Therapy delivery
  • Memory storage
  • Microprocessor
  • Power management

Microsystems in healthcare help meet the requirements for medical device integration since implantable devices are lightweight, small, and power-efficient.

Thus, all the functionalities are deliverable in a small medical ASIC with a smaller footprint than other solutions. In comparison to ASIC for commercial use, applications for medical devices already have a process maturity less likely to require revisions, offer a robust solution, and provides more quality.

The use of ASICs in healthcare also plays a vital role by combining several functions into one chip. This technology will not be possible because the number of chips required to drive the machinery will be too cumbersome.

Overall, Linear MicroSystems can provide a solution that will further benefit the healthcare industry with the application of modern ASICs and ultrasonic technology. Click here to get in contact with our engineers today.

How SOC is Used in Glucose Monitoring Devices

When thinking of a medical device such as a continuous glucose monitor, you might not consider the technological advancements behind them. Technology like system on a chip, or SOC, is helping make massive improvements in the world of glucose monitoring.

Monitoring blood sugar levels in patients with diabetes is vital. Unmonitored and uncontrolled conditions can lead to complications, such as the following diseases:

  • Heart disease
  • Stroke
  • Glaucoma
  • Kidney damage
  • Nerve damage

Therefore, several different ways are available to properly  monitor blood sugar, including:

  • Blood glucose meter
  • Continuous glucose monitor
  • Freestyle libre
  • Urine test

Among several effective methods, the glucose monitoring device is gaining popularity for providing real-time glucose or blood sugar readings.

However, some patients find the conventional methods quite bothersome. Thus, advances in blood sugar monitoring technology can be a game-changer.

One of them is the glucose monitoring device to monitor the blood sugar levels by measuring the interstitial glucose level. A signal travels to a monitor or a mobile app where an alert sounds if the levels become too high or too low.

How glucose monitoring devices work

Glucose monitoring devices work with the application of sensors to check how fast and in which direction the glucose levels are trending. Moreover, it can let you check your sugar levels overnight. The values of the glucose readings appear after data is transmitted to a monitor or insulin pump.

The sensor inserts into the subcutaneous tissue or just under the skin. This is quite similar to the insertion of the insulin pump catheter in the upper buttock or abdominal area.

The glucose levels in the fluid surrounding the cell are measured every ten seconds and converted into an electrical signal. These signals will represent the amount of sugar in the blood.

This device uses a transmitter that attaches to the sensor and sends a signal to a pager-sized device at a person’s belt or waistline. The system will record an average glucose value automatically every 5 minutes for up to 72 hours.

It requires 3 days before the sensor will be removed and the information will be downloaded to a computer. This will then be used to collect data and make necessary adjustments if needed.

This is quite useful to identify the fluctuations and trends that might go unnoticed with standard tests as well as fingerstick measurements. As a result, it will enable you to take action to avoid severe high or low levels before it is too late.

Technological advancements using SOC

Applications without SOC, advancements in monitoring blood sugar levels would be slower to come about. In fact, conventional glucose monitoring methods around the world are costly, invasive, painful, and time-consuming.

The research helps determine the effectiveness of using continuous non-invasive glucose monitoring. SOC technology has been useful for introducing a wearable system for monitoring glucose levels based on a single wavelength photoplethysmography. The overall system uses a 180 nm CMOS process with a chip size of 4 square mm and consumes about 1.62 mW.

Furthermore, developers are working on an ASIC chip to provide a controlled blood glucose monitor as an implantable device. This ASIC-controlled blood sugar monitor using SOC is implantable in the upper arm or wrist area of the patient.
