Amplifiers

Welcome to the Amplifiers!

Fundamentals

In electronics, an amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output.


Types

There are a lot of different amplifier types, all with their own applications, characteristics and construction. This page lists the different amplifier types which are described on the amplifier guide.

Applications

Amplifiers are used in a wide variety of applications. This category contains pages explaining various amplifier and operational amplifier applications.

Circuit Design

The process of circuit design can cover systems ranging from complex electronic systems all the way down to the individual amplifiers within an integrated circuit.
