  • Differential sensing circuit for clock skew calibration relative to reference clock
    Patent number: 11121851
    Abstract: A system includes a differential clock source configured to provide a reference clock signal and an inverted version of the reference clock signal. The system also includes a quadrature clock source configured to provide a quadrature clock signal that is phase-shifted relative to the reference clock signal. The system also includes a differential sensing circuit coupled to the differential clock source and the quadrature clock source. The differential sensing circuit is configured to determine skew of the quadrature clock signal based on the reference clock signal, the inverted version of the reference clock signal, and the quadrature clock signal.
