A voltage amplifier is an electronic device or circuit that amplifies an input voltage signal, thereby producing a correspondingly larger output voltage signal. Such amplifiers are crucial for systems where signal strength is weak and requires enhancement for further processing.
Key features of voltage amplifiers:
High input impedance: Ensures minimal loading of the input signal source.
Low output impedance: Facilitates effective transmission of the amplified voltage to the load.
Voltage gain: Defined as the ratio of output voltage to input voltage.
