Abstract

See full text

A charge pump circuit may include an output node, a current source circuit, a current sink circuit, a first amplifier circuit, and a second amplifier circuit. The current source circuit may be configured to source current to the output node. The current sink circuit may be configured to sink current from the output node. The first amplifier circuit may be configured to adjust a first amount of current sourced by the current source circuit based on a voltage on the output node. The second amplifier circuit may be configured to adjust the first amount of current sourced by the current source circuit or a second amount of current sunk by the current sink circuit based on the voltage on the output node.
