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 ...

The debate still goes on as to which are better, valves or transistors. We don’t intend to get involved in that argument here. But if you can’t make your mind up, you should try out this simple ...

Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...

ISSCC, the International Solid-state circuits conference, is the IEEE’s annual showcase for all that is best in on-chip circuit design from across the globe. Thousands of engineers will flock there ...

If you think most components are too complicated and just want great sound, the no-frills Cambridge AXA35 integrated amplifier is exactly what you’re looking for. Ex-movie theater projectionist Steve ...

Every smartphone has both a built-in amplifier and digital-to-analog converter (DAC). The amplifier cranks the audio signal to a level so that your headphones (or the smartphone’s speakers) can ...
