Abstract
Embodiments herein provide a voltage regulation system comprising a charge pump a voltage regulator and a current regulator. The charge pump is configured to output a current signal to a capacitor. The voltage regulator is configured to sample an output of the capacitor, and compare the sampled voltage to a target voltage to generate a control signal. The current regulator is configured to sample a portion of the output current based on the control signal and regulate the current signal outputted by the charge pump.
