Zusammenfassung:PROBLEM TO BE SOLVED: To reduce the circuit footprint of a circuit including a capacitor.SOLUTION: A capacitor circuit 200 includes a capacitor 20, a current detection section 22 for detecting a capacitor current flowing into/out of the capacitor 20, and a current amplification section 24 for generating an amplified current proportional to the capacitor current. The amplified current is drawn from a current flowing into the capacitor circuit to produce the capacitor current, or the amplified current is drawn into the capacitor current to produce a current flowing out of the capacitor circuit.
