Abstract
A circuit device includes an oscillation circuit configured to generate an oscillation signal, a waveform shaping circuit configured to perform waveform shaping on the oscillation signal, and a regulator configured to supply a regulated power supply voltage to the waveform shaping circuit. The circuit device further includes an amplitude detection circuit configured to detect the amplitude of the oscillation signal and output an amplitude detection signal, and a power supply control circuit configured to perform control on the regulator based on the amplitude detection signal, such that the regulated power supply voltage becomes smaller than the amplitude of the oscillation signal.
