Patent ID: 7518421

Claim:
A charge pump circuit comprising: a pump up circuit comprising a first p-type metal oxide semiconductor (PMOS) transistor and a second p-type metal oxide semiconductor (PMOS) transistor coupled together in a cascode configuration, said pump up circuit configured for providing a pump up current as an output; and said first p-type metal oxide semiconductor (PMOS) transistor having a source that is connected to an up control signal; a first kicker capacitor coupled to said pump up circuit, said first kicker capacitor having a first end directly connected to a drain of said first p-type metal oxide semiconductor (PMOS) transistor, said first kicker capacitor directly connected to a source of said second p-type metal oxide semiconductor (PMOS) transistor, said first kicker capacitor having a second end directly connected to an inverter, said inverter connected to said up control signal, said up control signal directly connected to a second inverter, and said second inverter connected to said source of said first p-type metal oxide semiconductor (PMOS) transistor; said first kicker capacitor configured for one of: adding electrical charge to and removing electrical charge from said pump up circuit.
