In electronic components, a buffer is a circuit that maintains the characteristics of a signal while replicating an input signal to an output signal.
That is, it passes the output signal to another circuit or device without amplifying or attenuating the input signal.
Buffers are used for the following purposes:
Signal Amplification: When the magnitude of the input signal is small, Buffer increases the magnitude of the output signal by amplifying the input signal.
Signal Attenuation: If the magnitude of the input signal is too large, Buffer reduces the magnitude of the output signal by attenuating the input signal.
Signal distribution: One input signal can be divided into multiple output signals.
Signal Drive: Drives an output signal by converting an input signal into sufficient electrical energy before passing the output signal to another circuit or device.
Buffers are used in many electronic components and come in a variety of circuit configurations and types.
For example, a Voltage Follower constructed using an Op-amp is a type of Buffer in which one input and one output are duplicated as the same signal. Also, inverting/non-inverting buffers are used in digital circuits.
These buffers are used to pass digital signals to other circuits or devices without amplifying or attenuating the input signal.
