Patent ID: 7634038

Claim:
A system for providing a wideband phase-locked loop, comprising: a phase-frequency detector configured to generate an up signal and a down signal; a frequency-to-current converter configured to receive a reference signal and generate a plurality of control signals; a charge pump configured to: receive the up and down signals from the phase-frequency detector and one of the plurality of control signals from the frequency-to-current converter; and generate a first output signal and a second output signal; a loop filter configured to: receive the first and second output signals from the charge pump; and generate a proportional path signal to set a loop bandwidth, a 1 st integral path signal to set a stabilizing zero that controls a phase margin, and a 2 nd integral path signal to set an average voltage-controlled oscillator frequency; and a voltage controlled oscillator configured to generate an output signal based on the proportional path signal, the 1 st integral path signal and the 2 nd integral path signal.
