The Path Forward for Embedded AI
In April 2021, I published an article in Printed Circuit Design & Fab, where I proclaimed the future of AI is embedded. In short, my view is that embedded systems will leverage greater usage of AI on the end device, meaning they will rely less on cloud platforms or data centers for inference. Without a doubt, I believe the future of AI is still embedded, but not with the chipset or system architecture I would have thought. At the time of writing

How to Calculate a Virtual Array in MIMO Systems
RF and sensing systems that use MIMO functionality have some important design constraints concerning virtual antenna design and placement. In these systems, due to the need for finer resolution and higher transmit/receive gain, the trend has been to pack more antennas into an array for beamforming and the reception of low-level signals. There is a reason for this trend, and it relates to an important concept in antenna array systems. When

Get Ready for Custom Quantum Processor Units
Anytime a company wants to develop at the leading edge of technology, it requires a ton of development from the ground up. In the realm of quantum computing, this is still true; companies that want to operate in this area of technology have to build just about everything from scratch. But today, the industry has taken an important step towards accelerating development of quantum devices. On 28 March 2022, Dutch company QuantWare announced

Mastering Magnetism: Hall Effect Sensors and Applications for PCBs
Magnetism allows you to do some really cool things—especially when electrons move through a magnetic field. One device that uses the deflection of electron motion for sensing is a Hall effect sensor. These little devices are used in automotive, manufacturing, consumer electronics, and other industries. The Hall effect basically allows a magnetic field to be sensed, which offers several possible applications. Some of the possible applications

Routing Requirements for a USB Interface on a 2-Layer PCB
In an earlier blog, I discussed some of the basic points in preparing routing rules for 2-layer PCBs to support routing and layout with digital signals. In particular, we looked at some of the basic stackup and routing rules needed to support a digital interface like I2C or SPI on a 2-layer PCB. When working with these interfaces, a few simple guidelines can help ensure signal integrity in your board and cut down on EMI. What about an impedance

Composite Amplifiers and How They Give the Best of Both Worlds
There are many times where you need an amplifier with high gain, low noise, high slew rate, and broad bandwidth simultaneously. However, not all of these design goals are possible with all off-the-shelf components. One solution is creative use of multiple amplifiers in a composite amplifier design. With the right composite amplifier, you can create a unique amplifier that exploits the best characteristics of each amplifier stage. Here are some

Current Limiting Resistor LED Systems with Matching Voltage Power Supply
Most of my friends in engineering live a balanced lifestyle. However, there are some engineers that are workaholics. These engineers do not limit their working hours and are constantly dealing with stress. Their lifestyle is not so different from an LED’s that is directly connected to a power supply without a current limiting resistor or with the wrong resistor value. They start out strong, but eventually flicker and burn out. In the architecture
