Abstract:
A core voltage generation circuit includes a comparator configured to perform a differential comparison of a reference voltage and a feedback core voltage. An amplifier is configured to amplify the external power supply voltage in response to an output signal of the comparator to generate the core voltage. A control switch is configured to form a current path of the comparator using different switch units according to a voltage level of an external power supply voltage input to the core voltage generation circuit.
