Abstract

A charge pump circuit for increasing a circuit voltage, comprising: a DC-DC up-converter (14) having an array of capacitors arranged to charge-pump to a higher voltage than the circuit voltage, the DC-DC up-converter having an output lead (8) arranged to output the higher voltage, a DC-DC down-converter (30) connected to the output lead, the DC-DC down-converter having an array of capacitors and diodes arranged to down-pump the higher voltage, and an ESP (Electrostatic Discharge Protection) circuit comprising a series (42) of N series-connected diodes arranged to sink current from the output lead, wherein N is an integer larger than two, each diode having its anode permanently connected to the output lead and its cathode permanently connected to a reference potential, wherein the series includes the diodes of the DC-DC down-converter.
