Multiphase signal divider

A phase locked loop circuit, comprising:

• a voltage controlled oscillator able to generate a multiphase signal, a divider of the multiphase signal by a constant factor, a phase rotating device having at an input the multiphase signal from the output of the divider and adapted to generate a control signal of the voltage controlled oscillator, wherein the multiphase signal divider comprises a circuit adapted to divide the first component of the input multiphase signal by the given division factor thus obtaining the first component of the output multiphase signal, and a plurality of N−1 devices, the first device of the plurality of N−1 devices adapted to sample the first component of the output multiphase signal with a component of the input multiphase signal thus obtaining the component of the output multiphase signal corresponding to the one component of the input multiphase signal, every other device of the plurality of N−1 devices adapted to sample the component of the output multiphase signal of the preceding device with another component of the input multiphase signal, phase shifted by a further constant factor with respect to the component of the input multiphase signal used in the preceding device, thus obtaining another component of the output multiphase signal corresponding to the other component of the input multiphase signal.
