Nordic Semiconductor has announced that Globalstar, a satellite and commercial IoT communications company, has selected Nordic’s Bluetooth Low Energy (Bluetooth LE) nRF52832 System-on-Chip (SoC) to provide the processing power and Bluetooth LE wireless connectivity for its “ST100 Satellite Transmitter” module....

Multi-Pronged Evolution From advanced infotainment systems to driver-assisted vehicle controls, the embedded electronics in today’s new car designs are being tasked to do more and more. To meet these evolving design challenges, IC vendors have rolled out a variety of...

A negative impedance converter (NIC) is a clever circuit, the analysis of which is a favorite exercise set by engineering lecturers everywhere. It’s not often used in practice, but it’s well worth having in your design kit-bag. I’ll show you...

Analog frequency-selective filters are useful for noise reduction, antialiasing before digitizing a signal, frequency response correction, and more. In this article, Robert explains the differences between filters and how to design them with computer-aided tools. Welcome back to the Darker...

XP Power has Introduced its LCS series of regulated output, convection cooled AC-DC power supplies that are well-suited to budget-conscious applications. The four new series (LCS35, LCS50, LCS75 and LCS100) offer power levels of 35W, 50W, 75W and 100W, respectively...

Maxim Integrated Products has introduced three precision measurement ICs: MAX41400 instrumentation amplifier, MAX40108 precision op amp and MAX31343 real-time clock (RTC) with integrated MEMS oscillator. Designers can use the ICs to achieve double the battery life together with robust protection...

CUI has announced the addition of two new EN 62368-1 certified, compact, regulated converter series to its compact isolated DC-DC converters line. The PQQ6W-S and the PQQ10W-S both offer cost-effective solutions for a wide range of applications, including IoT, consumer,...

Microchip Technology has introduced its high-side current sense amplifiers. They feature what the company claims is the industry’s lowest offset for AEC-Q100 Grade 0 qualified high-side current sense amplifier devices. The MCP6C02 amplifier is offered in both a Grade 1...

Using an Arduino Mega Centuries before the science of color temperature was understood, blacksmiths already knew how to read the temperature of a heated piece of metal by its color emissions. In this article, Jeff discusses the math and science...
