Abstract
A signal generation circuit includes: a reference voltage generation circuit configured to generate a reference voltage; a ramp voltage generation circuit configured to generate a ramp voltage that varies within a predetermined voltage range; and a comparison circuit configured to output a comparison result signal that indicates the magnitude relationship between the reference voltage and the ramp voltage. The reference voltage generation circuit gives the reference voltage a waveform of a triangular wave and varies the frequency of the triangular wave.
