Abstract
A semiconductor circuit apparatus having a clock oscillating circuit includes a first inverter circuit having a power supply terminal connected to a power supply potential via a first power supply potential connection transistor and a ground terminal connected to a ground potential via a first ground potential connection transistor, an inverter circuit block having a second inverter circuit connected to the power supply potential via a second power supply potential connection transistor and to the ground potential via a second ground potential connection transistor and connected to the first inverter circuit in parallel and a selection circuit block that outputs a power supply potential connection signal to any one of gate terminals of the first and second power supply potential connection transistors and a ground potential connection signal to any one of gate terminals of the first and second ground potential connection transistors.
