ABSTRACT:
A charge pump comprising a charge pump core including output switches. The charge pump core, in response to a drive signal, to generate a charge pump output. A limit swing generator, in response to an input signal, to generate the drive signal to control the charge pump core. The drive signal having voltage levels including a high level and a low level. The limit swing generator including at least one voltage generator to control the voltage levels of the drive signal such that the drive signal tracks a process variable of the output switches. The at least one voltage generator including at least one diode or diode connected device.
