It is an amplifier designed to maximise voltage gain. Also see "amplifier."
An amplifier in which the output-signal voltage is greater than the input-signal voltage.
A circuit incorporating one or more active devices and designed to amplify voltage waveforms.
An amplifying state in which the primary function is to increase signal voltage.
Amplifier designed to build up signal voltage. By design amplifiers can have a large voltage gain or a large current gain or a large power gain. Voltage amplifiers are designed to maximize voltage gain often at the expense of current gain or power gain.
