Abstract
A semiconductor device includes a first power supply terminal, a second power supply terminal, and first and second capacitors. The first power supply terminal is configured to be supplied with a first electrical potential. The second power supply terminal is configured to be supplied with a second electrical potential. The second electrical potential is different from the first electrical potential. The first and second capacitors are coupled in series between the first and second power supply terminals.
