Patent ID: 7397319

Claim:
A system for compensating the gain of a phase lock loop (PLL), comprising: a plurality of voltage controlled oscillators (VCOs) operatively coupled to a plurality of gain compensator cells, each VCO corresponding to a respective gain compensator cell, wherein the VCOs are operatively coupled to a tuning circuit, the VCOs being tuned by the tuning circuit, the tuning circuit adding or removing capacitance according to a capacitance control signal, and wherein at least one gain compensator cell comprises switches and current groups, the switches being operatively coupled to the current groups, the switches being operatively coupled to the capacitance control signal, each current group corresponding to a respective switch, each current group comprising a plurality of identical current sources, the identical current sources of each current group being configured in a current mirror arrangement, each current group being operatively coupled to a voltage, the voltage being a function of one or more PLL characteristics.
