Rectifier circuits are used in the design of power supply circuits. In such applications, the voltage being rectified is usually much greater than the diode voltage drop, rendering the exact value of the diode drop unimportant to the proper operation of the rectifier.
Other applications exist, however, where this is not the case. For example, in instrumentation applications, the signal to be rectified can be of very small amplitude, say 0.1 V, making it impossible to employ the conventional rectifier circuits. Also the need a rises for very precise transfer characteristics.
