Abstract

PURPOSE: To accurately rectify signals at low levels, by inserting an impedance element in series into a rectifier, and by generating voltage drop in the direction opposite to the voltage drop of a rectifier at the both ends of the impedance element by using an operational amplifier.
CONSTITUTION: A resistance R and a power source E of an operational amplifier OP are connected to a cathode K of a semiconductor rectifier Dd, a non-inversion input terminal P of the operational amplifier OP is connected to an anode A of the rectifier Dd and an inversion input terminal N and an output terminal D of the operational amplifier OP are connected to a terminal B of the resistance R at the side opposite to a terminal connected to the cathode K. The anode A is used as an anode and the terminal B as a cathode. Ideal rectifying characteristics possessing the status that forward voltage drop is zero and opposite direction resistance is infinite can be obtained.
