Abstract

A circuit includes a power-on control circuit and a voltage generating circuit. The power-on control circuit is configured to cause a power-on control signal to follow a voltage level of a first supply voltage during a first time period that a voltage level of a second supply voltage is less than a threshold value, and to set the power-on control signal to have a voltage level of a reference voltage during a second time period that the voltage level of the second supply voltage is greater than the threshold value. The voltage generating circuit is configured to generate a voltage signal responsive to the power-on control signal.
