摘要： This invention discloses charge pump apparati, where a charge pump apparatus, including a positive charge pump circuit and a negative charge pump circuit, providing multiple positive and negative voltages, comprises: a capacitor set shared by said positive charge pump circuit and said negative charge pump circuit; multiple electronic switches connected to said capacitor set and a plurality of voltage sources; multiple output capacitors connected to selected ones of said multiple electronic switches and one or more output terminals; and a non-overlapping time sequence that controls the on and off states of said multiple electronic switches; wherein under the control of said non-overlapping time sequence, corresponding electronic switches are turned on and off to control the output of the positive and negative voltages provided by said output capacitors to generate output voltages that are pre-determined multiples of the one or more input voltages. With this invention, coupling capacitors are shared during the processes of charging and discharging, and operate at alternating intervals through time sequence-control. As a result, both positive and negative output voltages can be simultaneously adjusted to provide different boost levels. The charge pump is both low in cost and has a design that is simple and easy to produce.
