Original Abstract Submitted
A drive circuit includes a modulation circuit that modulates a base drive signal, and outputs a modulation signal, an amplification circuit that outputs a first amplified modulation signal obtained by amplifying the modulation signal, a level switching signal generation circuit that generates a level switching signal, a level shift circuit that outputs the first amplified modulation signal as a second amplified modulation signal when the level switching signal has the first potential, and outputs, as the second amplified modulation signal, a signal obtained by shifting a potential of the first amplified modulation signal when the level switching signal has the second potential, and a demodulation circuit that demodulates the second amplified modulation signal. A threshold when the level switching signal generation circuit switches from the first potential to the second potential is different from a threshold when switching from the second potential to the first potential.
