  • Multiphase signal divider
    Patent number: 8305117
    Abstract: A divider of an input multiphase signal by a given division factor so as to obtain an output multiphase signal, the divider having a circuit adapted to divide a first signal component of an input multiphase signal by an given division factor to obtain a first component of a output multiphase signal, and a plurality of N?1 devices including a first device adapted to sample the first component with a component of the input multiphase signal to obtain 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 is 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 to obtain the corresponding component of the output multiphase signal.
