Abstract
A circuit device includes an N-type well on a P-type substrate, a P-type well provided in the N-type well, a circuit element provided in the P-type well, a P-type well provided in an N-type well, and a circuit element provided in the P-type well. A ground power supply voltage is supplied to a P-type well. A power supply voltage different from the ground power supply voltage is supplied to a P-type well. The ground power supply voltage or a first potential that is greater than or equal to the potential of the ground power supply voltage and less than the potential of a high potential-side power supply voltage is supplied to an N-type well.
