摘要: To enhance phase-locked loop (PLL) performance, PLL duty-cycle calibration may be desirable. In some cases, higher reference clock frequency may assist in reducing phase noise and increasing power efficiency of the PLL. A frequency doubler may increase the PLL reference clock frequency, but the duty cycle error in the clock may result in a spur at a clock frequency offset. Low phase noise PLL architectures may include a static phase offset at the PLL input between the reference path and the feedback path, and the static phase offset may vary with PVT, which may limit the accuracy of duty cycle error detection. Correcting for the static phase offset may cause a disturbance at the PLL output. To address the duty cycle error caused by the higher reference clock frequency, a duty cycle calibration loop may be introduced. For the duty cycle calibration loop, phase offset information may be extracted.

摘要: 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.
