PROBLEM TO BE SOLVED: To make it possible to accurately extract a power supply signal (DC component) lowered by a path from a DCDC converter to a load end and make it available for voltage drop compensation.;SOLUTION: The voltage drop compensation circuit includes: an AC coupling capacitor for removing the DC component of a first input signal and outputting the AC component; an RC filter for removing the AC component of a second input signal and outputting the DC component; and a voltage follower which receives the coupling of an output of the AC coupling capacitor and an output of the RC filter and lowers impedance and outputs it as a signal for feedback.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
