<p><P>PROBLEM TO BE SOLVED: To provide a capacitor circuit that can avoid the worsening of detection precision for voltage detection caused by temperature change. <P>SOLUTION: This capacitor circuit 91 for detecting a voltage includes the first capacitor circuit and the second capacitor circuit. The first capacitor circuit 1 includes a capacitor 11, and the second capacitor circuit 2 includes a capacitor 21. The first capacitor circuit 1 and the second capacitor circuit 2 are connected in series each other, both ends of a series circuit therein are led to input terminals T1, T2, and a node P1 in the series circuit is led to an output terminal T3. A ratio C1/C2 of an electrostatic capacity C1 in the first capacitor circuit 1 to an electrostatic capacity C2 in the second capacitor circuit 2 is substantially constant within a prescribed range. <P>COPYRIGHT: (C)2003,JPO</p> |
