Abstract
An electronic device is provided for improving the determining speed of the comparator and reducing power consumption. The comparator includes a differential input circuit configured to operate with a first power supply voltage and output a signal when an input signal is higher than a reference signal in voltage; a positive feedback circuit configured to operate with a second power supply voltage lower than the first power supply voltage and to accelerate transition speed when a compared result signal indicating a compared result between the input signal and the reference signal in voltage, is inverted, based on the output signal of the differential input circuit; and a voltage conversion circuit configured to convert the output signal of the differential input circuit into a signal corresponding to the second power supply voltage.
