Abstract:
Disclosed is a capacitance sensor including: a capacitance-voltage/current converter which converts a capacitance value of a sense capacitor into a voltage signal or a current signal by using an input signal; a multiplier which applies a weight to an output signal of the capacitance-voltage/current converter and outputs the weighted output signal; and an accumulator which accumulates continuously the output signal of the multiplier.
