<P> The precision rectifier, also known as a super diode, is a configuration obtained with an operational amplifier in order to have a circuit behave like an ideal diode and rectifier . It is useful for high - precision signal processing . </P> <P> The op - amp - based precision rectifier should not be confused with the power MOSFET - based active rectification ideal diode . </P>

Why precision rectifier is better than ordinary rectifier
