摘要： In particular embodiments, a charge pump includes a first input transistor operable to receive an up signal and in response to receiving the UP signal, transmit a corresponding output current from a positive power supply to an output node. The charge pump further includes a second input transistor operable to receive a down signal and in response to receiving the DN signal, transmit a second corresponding output current from a negative power supply to the output node. Additionally, the charge pump includes a first cascode transistor and a second cascode transistor positioned in a first current path between the first input transistor and the output node, and a third cascode transistor and a fourth cascode transistor positioned in a second current path between the second input transistor and the output node. The charge pump further includes a current mirror coupled to gates of the first, second, third, and fourth cascode transistors.
