Abstract
A power-on reset circuit arranged to generate a reset signal according to a power supply voltage includes: a power supply voltage detector, a holding circuit, a reference voltage generator and a reset determination circuit. The power supply voltage detector is controllable by the reset signal, and arranged to detect a level of the power supply voltage to generate a detection signal. The holding circuit is arranged to output an enablement signal according to the detection signal, wherein the holding circuit selectively maintains a level of the enablement signal according to a level of the detection signal. The reference voltage generator is controllable by the enablement signal to selectively output a reference voltage. The reset determination circuit is arranged to output the reset signal according to the power supply voltage and the reference voltage.
