摘 要:

PROBLEM TO BE SOLVED: To provide a CV converter with a simple circuit

configuration for reducing jitter noise and high-frequency noise.;SOLUTION: The CV converter is configured so that a

change in the capacitance of a capacitive element is converted to a voltage and by giving an alternating constant current to a counter electrode of a device to be

measured, by adding the voltage of both ends of the counter electrode after the balance adjustment and by further adding an alternating constant current converted to a voltage and by performing an AM detection thereof. Preferably the device to be measured is an electrostatic capacitor sensor.;COPYRIGHT: (C)2010,JPO&INPIT 主权项:

計測しようとする装置の対電極に交流定電流を与え、前記対電極の両端の電圧をバランス調整して加算したものに、前記交流定電流を電圧に変換したものをさらに加算し、それをAM検波することにより、容量素子の容量
