Phase-generation circuitry with duty-cycle correction and method for generating a multiphase signal |
摘要 |
Embodiments of phase-generation circuitry and methods for generating a multiphase signal with duty-cycle correction are generally described herein. The phase-generation circuitry may include a plurality of controllable delay stages arranged in series and phase detector circuitry. Each delay stage may be configured to phase shift a differential signal based on a control signal. The phase detector circuitry may be configured to generate the control signal based on a first time difference and a second time difference. The first time difference may be a time difference between rising edges of a first component of the differential signal and a second component of a phase-shifted signal. The second time difference may be a time difference between falling edges of the first component of the differential signal and the second component of the phase-shifted signal. Other circuits, systems, and methods are described. |
