Abstract:
A differential charge pump circuit for use in a phase-locked loop (PLL) circuit is disclosed. The circuit includes a reference current, two sense amplifiers, a common mode control amplifier, and an h-bridge circuit. The h-bridge circuit is coupled to the reference current and the common mode control amplifier. The reference current drives a first portion of the h-bridge circuit and the common mode control amplifier controls a second portion of the h-bridge circuit. The h-bridge circuit also includes first and second nodes. The circuit controls a voltage at the first node so that it is substantially equal to a voltage at the second node for a plurality of voltages at the second node.

Claim (Index 25):
A phase-locked loop circuit, comprising:\n a phase detector configured to generate a first output signal related to a difference in phase between a received reference signal and a received feedback signal; a filter circuit; a variable frequency oscillator configured to generate a second output signal, wherein the feedback signal received by the phase detector is based on the second output signal; and a differential charge pump circuit configured to generate a signal across the filter circuit that is based on the first output signal, the differential charge pump circuit comprising:\n a sensing operational amplifier; and \n an h-bridge circuit, comprising:\n a first node; \n a second node, wherein the differential charge pump circuit is configured to control a voltage at the first node so that it is substantially equal to a voltage at the second node for a plurality of voltages at the second node; and \n a first transistor coupled to the first node and the second node, wherein the voltage at the first node is controlled using the sensing operational amplifier and the first transistor.
