Abstract:
A signal processing device includes a detection circuit, a correction circuit, and a comparator circuit. The detection circuit generates a first detection signal, based on an output signal of a capacitive detection element that detects inertial force. The correction circuit corrects non-linearity of the first detection signal and outputs a second detection signal thus corrected. The comparator circuit compares the first detection signal and the second detection signal with each other and outputs a comparison signal representing a result of comparison.
