Abstract
A charge pump comprises a limit swing generator that receives an input signal and that generates a drive signal based on the input signal. A charge pump core includes output switches that generate a charge pump output in response to the drive signal. The drive signal includes a voltage level. The limit swing generator includes at least one voltage generator to control the voltage level of the drive signal such that the drive signal tracks a parametric variable of the output switches.
