ABSTRACT:
A semiconductor integrated circuit device including a power supply voltage converter and internal circuits. The converter converts an external power supply voltage to an internal power supply voltage of a predetermined value. The internal circuits are driven by the internal power supply voltage. The internal circuits include a clock generator. The converter comprises a reference voltage generator, an output circuit for lowering the external power supply voltage, thereby outputting the internal power supply voltage, and an error signal amplifier for comparing the internal power supply voltage with the reference voltage generated by the reference voltage generator and for controlling the conductance of the output circuit to make the compared voltages equal. The error signal amplifier includes a control signal generator for generating control signals in response to the clock pulses output by the clock generator, and a current control circuit for changing, in accordance with the control signals, the current supplied from an external power supply to the error signal amplifier.
