Abstract
A phase-locked loop circuit comprises an analog part, an integral part, and a voltage controlled oscillator configured to receive a first current signal from the analog part and a second current signal from the integral part, and to output an output clock. The integral part is configured to receive a first and a second update signal each having at least one state based on a phase difference between an input clock and the output clock. The integral part comprises three integrator cells interconnected to form a ring oscillator.
