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 ...
A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...
Fig 1. This basic source-follower circuit is the kind of amplifier you would find in an electric bass guitar amplifier. R6 provides the feedback. On the other hand, low-distortion applications require ...
