を特徴とするサーボ回路。 In a servo circuit that has a plurality of servo systems operating in parallel, and one end of the controlled object of each servo system is connected to a common potential terminal, the servo driver that supplies drive current to each of the controlled objects is connected to an inverting amplifier or a non-converting amplifier. The inverting amplifier and the non-inverting amplifier are configured in such a way that the algebraic sum of the terminal voltages at the other end of each controlled object is closest to the voltage value at the common potential end. A servo circuit characterized by:
