Abstract
An integrated CMOS clock generator with a self-biased phase locked loop circuit comprises a phase-frequency detector with a reference signal input, a feedback signal input and an output. A first charge pump of the clock generator has an input connected to the output of the phase-frequency detector and an output that supplies a control voltage. A loop capacitor is connected to the output of the first charge pump. The clock generator further has a second charge pump with an input connected to the output of the phase-frequency detector and an output. In particular, the clock generator has two oscillator blocks.
