Patent ID: 7365582

Claim:
A charge pump comprising: a first pair of differential transistors, each including a control terminal and first and second terminals; a second pair of differential transistors, each including a control terminal and first and second terminals; first and second charge pump drivers that communicate with said control terminal of one of said first pair of differential transistors and one of said second pair of differential transistors, respectively, wherein each of said first and second charge pump drivers comprise: a third pair of differential transistors, each including a control terminal and first and second terminals; and a first control circuit that generates a first control signal for said control terminal of one of said third pair of differential transistors and a second control signal for said control terminal of the other of said third pair of differential transistors; third and fourth charge pump drivers that communicate with said control terminal of the other of said first pair of differential transistors and the other of said second pair of differential transistors, respectively, wherein each of said third and fourth charge pump drivers comprise: a fourth pair of differential transistors, each including a control terminal and first and second terminals; and a second control circuit that generates a third control signal for said control terminal of one of said fourth pair of differential transistors and a fourth control signal for said control terminal of the other of said fourth pair of differential transistors.
