  • Patent number: 10411593
    Abstract: A system and method for a decimated phase detector circuit includes a bang bang phase detector (BBFD), an UP rolling counter connected to an UP output of the BBFD, and a DOWN rolling counter connected to a DOWN output of the BBFD. A charge pump is connected to the UP rolling counter and the DOWN rolling counter and is configured to receive a decimated UP signal from the UP rolling counter and a decimated DOWN signal from the DOWN rolling counter. The charge pump is further configured to provide a control voltage according to the received decimated UP signals and decimated DOWN signals.

  • Publication number: 20190273639
    Abstract: A two-stage decision feedback equalizer. The decision feedback equalizer is configured to receive serial data, at an analog input, at a first data rate. The two-stage decision feedback equalizer has an analog input and four digital outputs, and includes a first stage and a second stage. The first stage is connected to the analog input, and includes a half-rate predictive decision feedback equalizer consisting of current mode logic circuits. The second stage is connected to the first stage, and consists of complementary metal oxide semiconductor circuits.
