Abstract
The present disclosure provides a power supply circuit and an undershoot suppression circuit thereof. The undershoot suppression circuit includes a rising edge determination circuit, a falling edge determination circuit and a pulse generation circuit. The rising edge determination circuit detects a difference voltage between an output voltage of the power supply circuit and a reference voltage, and outputs a clock control signal with a first voltage level when the difference voltage is greater than a threshold voltage. The falling edge determination circuit detects the output voltage, and outputs a reset signal with the first voltage level when the output voltage is not smaller than the reference voltage. The pulse generation circuit generates an undershoot suppression pulse according to the clock control signal with the first voltage level and the reset signal with the first voltage level, so that the output voltage approaches the reference voltage.
