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 ...

Last time I showed you how to set up a reasonably complex design in a spreadsheet: a common emitter bipolar transistor amplifier. Having the design in a spreadsheet makes it easy to do “what if” ...

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 ...

Members can download this article in PDF format. Use of differential signaling in analog front ends is increasing across a range of applications, from audio processing to factory automation.

The first transistor was successfully demonstrated at Bell Laboratories in Murray Hill, New Jersey, in 1947. This three-terminal device has spawned many of the electronics devices that make possible ...

Rotel just released the high performance RB-1582MKII (200-watt x 2) and RB-1552MKII (120-watt x 2) class A/B stereo power amplifiers. Each amplifier is built with an engineering philosophy called ...

Bipolar transistors, essential components in a myriad of electronic devices, are highly susceptible to the adverse impacts of radiation. Ionising radiation introduces defects within the semiconductor ...
