The circuit aims to produce a power amplifier with the use of an operational amplifier NE5534 at its input compared to classic designs which use differential amplifiers. NE5534 – a high performance ...

Although the ubiquitous LM386 IC was designed to be used as an audio amplifier, it has a number of undocumented characteristics that can be exploited to create simple radio receiver circuits that ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...

Usually targeted at audio applications, these circuit blocks find homes in all types of designs. Here’s a quick study of their operation and properties. Two of the most often used amplifier building ...
