It is now trivial and non-invasive to measure blood-oxygen saturation SpO2, thanks to LEDs, algorithms, and ICs for pulse oximetry — it’s a very long way from having to draw blood and send it out for assessment. Part 1 of this FAQ discussed the principle of the non-invasive, light-based pulse-oximetry systems for reading blood-oxygen saturation […]
Understanding and testing asynchronous logic
Traditionally, computer and instrumentation engineers work with synchronous logic, where a global clock circuit imposes a timing structure to which all circuits down to the components level adhere. In synchronous logic, an autonomous oscillator outputs a square wave that never varies in frequency or amplitude. At the rising edge (sometimes falling edge) a potentially vast […]
electronica 2018: 17 Halls, 3000 exhibitors, and several pairs of shoes for the “Big Step Challenge”
The world’s leading trade fair and conference for electronics will begin in Munich on Tuesday. In addition to 17 halls and over 3,000 exhibitors, electronica, which runs from November 13–16, also has an extensive supporting program. Big steps, reinforced shoes? electronica is expecting visitors from over 80 countries — that’s a lot of people taking […]

Blood oxygen meters, Part 1: Background and principles
It is now trivial and non-invasive to measure blood-oxygen saturation SpO2, thanks to LEDs, algorithms, and ICs for pulse oximetry — and it’s a very long way from having to draw blood and send it out for assessment. Just a few decades ago, determining the vital medical parameter known as blood oxygen level — formally […]
PODCAST: Sujit Banerjee: Lab to fab to energy efficient Silicon Carbide semis
Dr. Sujit Banerjee arrived in the U.S. from India wanting to make a difference. Years later, the self-proclaimed “non-marketing guy” approached a fab with not much more than a dollar in his pocket to invest and a dream of a silicon carbide power semiconductor technology to sell. And now, this CEO of Monolith Semiconductor (part […]

This year’s inaugural LEAP Awards competition honored ground-breaking new products that set a new standard for innovation. […]
Why clean PCBs matter, Part 2
The article Why Clean PCBs Matter, Part 1, covers the effects that a dirty Printed Circuit Board can have on electronics, especially those supporting high-frequency signals or sensitive analog components. Keeping a PCB clean begins in assembly when components are preferably soldered to the PCB in a clean environment. Of great importance is the type […]
