It used to be a rite of passage to be able to do the math necessary to design various bipolar transistor amplifier ...

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 ...

Sometimes I wish FETs had become practical before bipolar transistors. A FET is a lot more like a tube and amplifies voltages. Bipolar transistors amplify current and that makes them a bit harder to ...

It's been about 40 years since the first monolithic op amps were introduced. Those first devices, some of which are still in production, were designed exclusively in bipolar technology. Today most ...

Although most people aren’t aware of insulated gate bipolar transistors (IGBTs), they do enjoy their benefits. From air conditioners to electric cars to stereo amplifiers, the modern world relies on ...

Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better than conventional amplifiers thanks to ...
