Diodes are essential semiconductor devices used to control the direction of electrical current in circuits. This tutorial explains how diodes work, their different types, and why they are critical ...

In rectifier circuits, the voltage drop that occurs with an ordinary ... When the input signal Vin is positive, Op-Amp output terminal is negative, Diode D1 is reverse biased and D2 Diode is forward ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

"Such circuits are also used in controlling ... More information: Josep Ingla-Aynés et al, Efficient superconducting diodes and rectifiers for quantum circuitry, Nature Electronics (2025).

All is working beautifully (although output resistance is 1k, so buffering mught be required downstream, and none of the circuits in this blog get ... In the simple ‘precision rectifier diode’ case, ...
