A booster circuit includes a first transistor performing a first on-off operation based on a first control signal and a second transistor performing a second on-off operation based on the first control signal. The first on-off operation and the second on-off operation are reversed. A third transistor performs the first on-off operation based on a second control signal. The second control signal has a phase opposite the first control signal. A fourth transistor is included in a metal oxide semiconductor capacitor.
