Original Abstract Submitted
Embodiments of a multiphase clock generation device may include an input for feeding a reference clock, a clock generation unit adapted to generate phase-shifted clock signals from the reference clock, and a phase comparator unit functionally coupled with the clock generation unit. The phase comparator unit is adapted to measure a phase shift of the phase-shifted clock signals. The multiphase clock generation device includes a self-calibration unit that is functionally coupled with the clock generation unit. The calibration unit outputs a delay-calibration parameter to the clock generation unit. The clock generation unit is adapted to generate a multiphase clock signal out of the reference clock and the delay-calibration parameter.
