Abstract
A charge pump includes a first transistor, a first switch coupled between the first transistor and an output of the charge pump, a second transistor, and a second switch coupled between the output of the charge pump and the second transistor. The charge pump also includes a third transistor, wherein a gate of the third transistor is coupled to a gate of the first transistor, a fourth transistor, wherein a drain of the fourth transistor is coupled to a drain of the third transistor, and a bias circuit configured to bias a gate of the fourth transistor and a gate of the second transistor. The charge pump also includes an amplifier having a first input coupled to the output of the charge pump, a second input coupled to the drain of the third transistor, and the output coupled to the gate of the third transistor.
