In this post, we will take a gentle dive into logarithmic amplifiers—commonly known as log amps—those quietly powerful circuits that work behind the scenes to decode exponential signals and tame wide ...

JFETs are, almost invariably, depletion mode devices, which means that there will be some drain current at a zero-applied gate-source potential. This current will decrease in a fairly linear manner as ...

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper. By ...

Diode-based sensors now have video bandwidths in excess of 35 MHz and, separately, a 90-dB dynamic range. However, there are many types of diode-based sensors, and they are not all created equal.

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

The Slow-Start Stabilizer project from 2013 is a compact circuit designed to improve both stability and reliability during power-up, making it a useful upg ...
