Abstract
A driving signal control circuit includes a discharge circuit, a counter circuit, and a control circuit. The discharge circuit is configured to compare a monitored voltage and a reference voltage, and generate a discharge signal. The monitored voltage is proportional to a core voltage. The counter circuit is configured to perform an up/down count operation according to the discharge signal, and generate a count signal. The control circuit is configured to generate a driving signal which has an enable period proportional to the count signal.
