Abstract: An output portion of a charge pump receives control signals from a phase frequency detector and in response outputs positive current pulses and negative current pulses to a loop filter. A current control portion of the charge pump controls the output portion such that the magnitudes of the positive and negative current pulses are the same. Within the current control portion there is a “Charge Pump Output Voltage Replica Node” (CPOVRN). The voltage on this CPOVRN is maintained to be the same as a voltage on the charge pump output node. A capacitor leakage compensation circuit indirectly senses the voltage across a leaking capacitor of the loop filter by sensing the voltage on the CPOVRN. The compensation circuit imposes the sensed voltage across a replica capacitor, mirrors a current leaking through the replica, and supplies the mirrored current in the form of a compensation current to the leaking capacitor.

Abstract: Certain aspects of the present disclosure generally relate to voltage-controlled oscillators (VCOs) using a lowered or an adjustable negative transconductance (?gm) compared to conventional VCOs. This ?gm degeneration technique suppresses the noise injected into an inductor-capacitor (LC) tank of the VCO, thereby providing lower signal-to-noise ratio (SNR) for a given VCO voltage swing, lower power consumption, and decreased phase noise. One example VCO generally includes a resonant tank circuit, an active negative transconductance circuit connected with the resonant tank circuit, and a bias current circuit for sourcing or sinking a bias current through the resonant tank circuit and the active negative transconductance circuit to generate an oscillating signal. The active negative transconductance circuit includes cross-coupled transistors and an impedance connected between the cross-coupled transistors and a reference voltage.
