You sometimes need to measure the differential temperature between two points in a system to a greater accuracy than that required in measuring the absolute temperature at either of the individual points...
RTDs provide differential temperature measurement
Renesas releases its first Wi-Fi 6 and Wi-Fi/Bluetooth LE combo MCUs for IoT and connected home applications
Renesas Electronics introduced the RA6W1 dual-band Wi-Fi 6 wireless microcontroller, along with the RA6W2 MCU that integrates both Wi-Fi 6 and Bluetooth Low Energy (LE) technologies...
Current source has high compliance
Current sources are useful in many areas of electronics, such as voltage and current division, current transmitters, excitation of thermistors, RTDs, bridges, potentiometers, and circuit biasing...
Minimizing emissions from a Ćuk regulator
The Ćuk topology is ideal for generating a negative output voltage from a positive supply voltage...
Silly simple precision 0/20 mA to 4/20 mA converter
This Design Idea offers an alternative solution for an application borrowed from frequent DI contributor R. Jayapal, presented in: “A 0-20 mA source current to 4-20 mA loop current converter”...
A 0-20mA source current to 4-20mA loop current converter
A 4 to 20 mA loop current is a popular terminology with Instrumentation/Electronics engineers in process industries. Field transmitters like pressure, temperature, flow, etc., give out 4 to 20 mA current signals...
Gold-plated PWM-control of linear and switching regulators
Alright, I admit that the title is a bit over the top. So, what do I mean by it? I mean that: The application of PWM control to a regulator does not significantly degrade the inherent DC accuracy of its output voltage...
Circuit improves on bias for GaAs FETs
It's important to properly sequence the bias applied to an RF/microwave GaAs FET or a MMIC amplifier. These devices are extremely sensitive to drain and gate voltage levels...
Circuit offers series protection against power-line transients
Voltage transients on low-voltage power lines can sometimes attain amplitudes many times the nominal voltage level. That behavior often calls for protection against the application of improper power levels...
Microchip halves the power required to measure how much power portable devices consume
Battery-operated devices and energy-restricted applications must track and monitor power consumption without wasting power in the process. To solve this challenge, Microchip Technology announces two digital power monitors...
