Abstract
Disclosed is a circuit which receives a supply voltage from a power supply and generates a voltage of a desired level different from that of the supply voltage. The circuit includes an oscillation circuit, a supply voltage generator, a first interconnection and a control circuit. The oscillation circuit generates an oscillation output signal. The supply voltage generator is responsive to the oscillation output signal from the oscillation circuit and generates a voltage of a predetermined level. The first interconnection connects the supply voltage generator to an internal circuit which is to be supplied with the voltage generated by the supply voltage generator. The internal circuit is also connected via a second interconnection to a power supply. The control circuit is provided between the first interconnection and the second interconnection as a variable resistor circuit which is responsive to the oscillation output signal from the oscillation circuit. The control circuit changes its resistance in synchronism with the end of the generation of the voltage of the predetermined level by the supply voltage generator.
