voltage amplifier
1. An electronic circuit whose function is to accept an input voltage and produce a magnified, accurate replica of this voltage as an output voltage.

The voltage gain of the amplifier is the amplitude ratio of the output voltage to the input voltage.

2. An amplifier designed primarily to build up the voltage of a signal or to increase a signal's voltage, without supplying appreciable power.
