摘要： A capacitor C and an impedance converter Hiz are included in a feedback circuit of the first operational amplifier OP1 in series; an electrode P1 of a capacitive sensor is connected to a connection point of the said capacitor and the converter via a signal line L. The signal line L is connected to a predetermined standard electric potential through resistance R3 whose resistance value is high. When the capacitor is included in the feedback circuit, the signal line becomes in a state of floating and a circuit operation becomes unstable, however, the signal line L is fixed at predetermined electric potential, and therefore, the operation becomes stable. It is acceptable to configure the impedance converter with a voltage follower and connect the resistance R3 to the output.
