Reading an article about the first transistorized Hi-Fi amplifier, [Netzener] got the itch to make one. But what to use for the starting point? Enter an old Radio Shack P-Box stereo amplifier kit.

Combining two TLx431 regulators together to make a programmable gain current mirror that can be also used for a current loop ...

It used to be a rite of passage to be able to do the math necessary to design various bipolar transistor amplifier configurations. This doesn’t come up as often as it used to, but it is still a good ...

A transistor that operates with photons rather than electrons is often heralded as the next step in information processing, but optical technology must first prove itself to be a viable solution in ...

Abstract: Organic electrochemical transistors (OECTs) are attractive devices for the next generation of biosensors, but their widespread adoption has been limited by the need for expensive and bulky ...
