Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

Modern circuit design is a “mixed signal” endeavor thanks to the availability of sophisticated process technologies that make available bipolar and CMOS (Complementary Metal Oxide Semiconductor), ...

Last time we looked at Spice models of a current sink. We didn’t look at some of the problems involved with a simple sink, and for many practical applications, they are perfectly adequate. However, ...

A major current law has been rewritten thanks to the three-port transistor laser. Data the transistor laser generated did not fit neatly within established circuit laws governing electrical currents, ...

The handedness or “chirality” of electrons affects how current flows in graphene transistors, according to new work done by researchers in the UK and Russia. The team’s findings could help to make ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...
