Abstract
DC to DC converter circuitry includes a dual phase charge pump and at least one pair of multiplier phase circuits. The dual phase charge pump is coupled to each one of the at least one pair of multiplier circuits and adapted to receive a DC input voltage and only four control signals, and produce a stepped-up output voltage. Each one of the at least one pair of multiplier phase circuits are adapted to receive the stepped-up output voltage, a cross-coupled control signal from the other multiplier phase circuit in the pair of multiplier phase circuits, and a different one of the control signals and further multiply the stepped-up output voltage to produce a multiplied stepped-up output voltage with a magnitude that is approximately three times that of the DC input voltage or greater.
