Although semiconductor diodes available today are close to ideal” devices, they have severe limitations in low level applications. Silicon diodes have a 0.6V threshold which must be overcome before appreciable conduction occurs. By placing the diode in the feedback loop of an operational amplifier, the threshold voltage is divided by the open loop gain of the amplifier.
