Error amplifier (electronics)
- Error amplifier (electronics)
An error amplifier is most commonly encountered in feedback unidirectional voltage control circuits where the sampled output voltage of the circuit under control is fed back and compared to a stable reference voltage. Any difference between the two generates a compensating error voltage which tends to move the output voltage towards the design specification.
