Every amplifier has different class and application. Generally transistors and op-amps are used to build amplifier. Here, in this project we learn about Bootstrap Amplifier. Typically Bootstrapping is ...

A transistor amplifier circuit is an electronic circuit that uses one or more transistors to amplify an input signal. The basic operation of a transistor amplifier circuit involves using a small input ...

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 ...

There are many different audio power amplifier ICs to choose from, but designing an audio power amplifier using an operational amplifier (op-amp) and bipolar transistors is quite advantageous.

This article describes a low-cost low noise audio distribution amplifier based on hybrid or mixed technology. Input to the amplifier is from low-noise, high-gain npn transistor. Output buffers are ...

This single transistor audio mixer is used in an amplifier circuit design with base driven transistor and with its emitter being current controlled, most of the driving current flows through the ...

In the measurement industry, a very crucial functional block is a Programmable Gain Amplifier (PGA). If you are an electronic enthusiast or a college student, you have probably seen a multimeter or ...
