Abstract
A self-biased phase locked loop (PLL) circuit includes a charge pump to generate a control voltage, a controlled oscillator coupled to the charge pump to generate the output signal based at least in part upon the control voltage, discharge circuitry coupled to the charge pump to discharge the control voltage, and frequency detection circuitry coupled to the controlled oscillator and the discharge circuitry to generate a digital feedback signal for terminating discharge of the control voltage by the discharge circuitry when the output signal reaches a threshold frequency that is a fraction of the target frequency.
