A charge pump phase locked loop based on self biased technique is presented. In this technique, the operating bias levels are essentially established by the operating frequency of the voltage controlled oscillator, namely, all bias voltages and currents are determined by VCO controlling voltage. Thus, a fixed damping factor and a fixed ratio of the bandwidth to operating frequency are obtained, which are defined by th...
