ABSTRACT:
An integrated, high speed, zero hold current and delay compensated charge pump operable at one of two different selectable pumping currents. The charge pump includes first and second supply terminals, a first input terminal for receiving digital charge-up control signals, a second input terminal for receiving digital charge-down control signals, and an output terminal. A first transistorized differential amplifier controls a first current flow of a first polarity between the first supply terminal and the output terminal as a function of the charge-up control signals. A second differential amplifier controls a second current flow between the first and second supply terminals as a function of the charge-down control signals. A pump current mirror produces a mirrored second current flow of a second polarity between the output terminal and the second supply terminal as a function of the second current flow.
