A TU Delft team has demonstrated a one-way superconductor that gives zero resistance in one direction, but blocks current completely in the other. The discovery, long thought impossible, heralds a ...

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: t… ...

An acoustic diode, enabling the one-way transmission of sound waves, could dramatically improve the quality of medical ultrasound imaging and lead to better sound dampening materials.

A diode allows current to flow one way but not the other in an electrical circuit. It's essentially half of a transistor, the main element in computer chips.

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 an article published in Communications Physics, a multi-institutional research team led by The University of Osaka announces the successful observation of the so-called superconducting diode ...

A two-way current mirror with two BJTs and one diode that can mirror the more positive input side at its output.

In his endless quest for more optical power, [Les] happened upon a paper describing a simple driver circuit that can dump massive amounts of current into a laser diode to produce far more optical ...

Recently (5/21/25), I published a Design Idea (DI) describing a bidirectional current mirror using just two transistors and a diode, “A two-way mirror—current mirror that is.” That circuit works well ...
