Abstract
A charge pump circuit includes a charge pump configured to increase a voltage of an input signal to generate a voltage-boosted input signal, output the voltage-boosted input signal in response to a determination that the voltage-boosted input signal is greater than or equal to a threshold, and connect the charge pump to a supply voltage to pre-charge the charge pump in response to a determination that the voltage-boosted input signal is less than the threshold. The charge pump circuit includes bandgap reference generator configured to receive the voltage-boosted input signal and output, based on the voltage-boosted input signal, a voltage reference signal to a device that operates in accordance with the supply voltage.
