  • Patent number: 11481015
    Abstract: A redriver chip includes a controller and a plurality of circuits coupled to the channel. The controller adjusts a set of parameters of the plurality of circuits to have first values during a first mode of operation and second values during a second mode of operation. The first values generate a first level of power consumption during the first mode of operation, and the second values generate a second level of power consumption during the second mode of operation. The first level of power consumption is lower than the second level of power consumption, and the first mode of operation corresponding to a low-power mode of the redriver chip.

  • Patent number: 11206161
    Abstract: An adaptive equalizer and automatic gain controller is disclosed. The adaptive equalizer and automatic gain controller includes a programmable continuous time linear equalizer (CTLE). The CTLE includes a control port to receive a control signal to adjust a frequency response of the CTLE. The adaptive equalizer and automatic gain controller also includes a power comparator coupled with an output of the CTLE and a controller coupled with the power comparator and the control port and configured to generate the control signal for the CTLE based on the output of the power comparator. The power comparator is configured to compare power of a low frequency part and a high frequency part of an output signal of the CTLE.
