Abstract: In a capacitance detection type sensor system, a sensitivity of the sensor system deteriorates because a low frequency noise typified by a 1/f noise cannot be separated in frequency from a signal band. A carrier wave used for capacity detection is modulated with two kinds of frequencies, sampled at a first modulation frequency, subjected to a C/V conversion, and synchronously detected at a second modulation frequency to obtain a signal.
