ABSTRACT:
Multistage charge pumps with diode loss compensation are disclosed. In one example, a pre-regulated charge pump to generate a voltage is described. The example pre-regulated charge pump includes a charge pump having a plurality of stages and one or more diodes. The stages are configured to generate an output voltage at an output terminal based on an input voltage and a number of the multiplier stages. The example pre-regulated charge pump also includes a pre-regulator stage configured to adjust the input voltage to remove dependency on supply voltage variation. The pre-regulator includes a feedback diode configured to compensate for one or more voltage drops associated with the one or more charge pump diodes.
