Abstract
A clock receiver including: a ring oscillator adapted to generate a clock signal, the ring oscillator having a sequence of N inverters, an input of a first inverter being coupled to a feedback node, an input of a second inverter being connected to an output of the first inverter and to an input line for receiving a reference clock signal, and an output of the second inverter or of a third inverter providing a first phase signal; a further sequence of inverters, an input of a first further inverter being coupled to the feedback node, and an output of another further inverter providing a second phase signal; and a control circuit for adjusting an oscillation frequency of the ring oscillator based on the relative phases of the first and second phase signals.
