ABSTRACT:
In order to prevent a signal of a signal wiring from receiving a bad influence due to a power supply capacitor, provided is a semiconductor including a high reference potential terminal and a low reference potential terminal composing power supply voltage terminals; a first MOS capacitor in which a gate of a p-channel MOS field effect transistor is connected to the low reference potential terminal, and a source and a drain are connected to the high reference potential terminal; and a first signal wiring connected to the gate via a parasitic capacitor and a signal in the low reference potential is supplied at the time of starting the power supply.
