ABSTRACT:
A dual mode charge-pump circuit and associated method and apparatuses for providing a plurality of output voltages, using a single flying capacitor, the circuit including a network of switches that is operable in a number of different states and a controller for operating said switches in a sequence of the states so as to generate positive and negative output voltages together spanning a voltage approximately equal to the input voltage and centered on the voltage at the common terminal, in a first mode and positive and negative output voltages each up to substantially the input voltage in a second mode.
