  • Publication number: 20220173744
    Abstract: A hybrid comparator includes an analog signal combiner and a dynamic latch. The analog signal combiner is configured to receive an input analog signal and an input reference signal, and generate an analog output signal by combining the input analog signal and the input reference signal. The dynamic latch is configured to receive the analog output signal and a clock signal, and generate a digital output signal.

  • Patent number: 11271710
    Abstract: A quadrature phase clock generator includes a tunable polyphase filter and a phase detector. The tunable polyphase filter is configured to receive an input clock signal and generate four quadrature phase clock signals. The phase detector is coupled to receive at least two of the four quadrature phase clock signals and generate a control signal adapted to tune the polyphase filter based on the received quadrature phase clock signals. Further, the phase detector is configured to provide the control signal to the polyphase filter in a feedback loop. Based on the control signal from the phase detector, the tunable polyphase filter generates four tuned quadrature phase clock signals as output phase clock signals.
