Abstract
A circuit device includes: a power supply circuit; and a logic circuit, the power supply circuit supplying a first power supply voltage and a second power supply voltage to the logic circuit, the first power supply voltage supplied by the power supply circuit periodically changing with a first reference voltage as a reference voltage, the second power supply voltage supplied by the power supply circuit periodically changing with a second reference voltage as a reference voltage, the power supply circuit supplying, due to resonance, the first power supply voltage and the second power supply voltage that repeat a first period during which a voltage difference between the first power supply voltage and the second power supply voltage is decreasing and a second period during which the voltage difference is increasing, and the logic circuit performing adiabatic circuit operation with the supply of the first and the second power supply voltage.
