Abstract
An electronic circuit is described in which a charge pump-based digital phase locked loop circuit is augmented with additional circuitry to monitor and control noise and power consumption. The additional circuitry includes a comparator and a measurement stage configured to measure and adjust a unity gain bandwidth of the phase locked loop. In one embodiment, the measurement stage includes two frequency-to-current converters and associated current mirrors.
