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 3):
The differential charge pump circuit of  claim 1 , the h-bridge circuit further comprising:\n a second sensing operational amplifier; a first inverse node, wherein the voltage at the first inverse node is the inverse of the voltage at the first node; and a second inverse node, wherein the voltage at the second inverse node is the inverse of the voltage at the second node, wherein the first inverse node and the second inverse node are inputs to the second sensing operational amplifier, and wherein the differential charge pump circuit is configured to control a voltage at the first inverse node so that it is substantially equal to a voltage at the second inverse node for a plurality of voltages at the second inverse node.
