Data Security, 5G and Onshore PCB Manufacturing with Dr. Rob Spalding
In this episode, we are very pleased to have Dr. Rob Spalding. He is a retired Brigade General at the US Air Force and now the CEO of SEMPRE (Secure EMP-Resistant Edge), a tech company based in Washinton DC that provides military-grade 5G and high-performance edge computing infrastructure for telecom operators, first responders, government and enterprise customers. Today, Rob and I will talk about all things security! Rob will tackle the
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
Flex and Rigid-Flex PCB Applications
There are many fun and interesting rigid-flex PCB applications. Learn more about these important application areas and how flexible designs can solve many practical problems.
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 2.0 Impedance 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
Machine to Machine Communication and Internet of Things Can Benefit from Wireless Connectors
Have you ever bought a new gizmo or gadget and wondered how you lived life before it? For me, smartphones obviously come to mind. When I was a kid I was content to play with sticks and rocks. Now my kids play with virtual sticks and rocks on their iPhones. High speed wireless connectors will be like that for the Internet of Things. Keyssa has developed a new short-range chip that operates in the 60 GHz band that they say will replace all

What Does AMD’s Purchase of Xilinx Mean for the Electronics World?
Who is Xilinx? While AMD is focused on microprocessor production, Xilinx is a specialist producer of FPGA (field-programmable gate arrays), which are particularly useful for telecommunications applications, and the development of 5G across the world has opened up significant growth in this sector. The expected number of new 5G cellular base stations required over the next five to ten years will be in the millions. Xilinx has been one of the front
