  • Systems, circuits and methods for adapting parameters of a linear equalizer in a receiver
    Patent number: 9258152
    Abstract: A receiver is optimized by adapting parameters of a linear equalizer component within the receiver. Data decisions and error decisions are generated. These data decision and error decisions are used to derive an error rate of data by measuring the number of margin hits that occur. A balance value is also calculated from the data decisions and the error decisions. The balance value is used to update parameters of the linear equalizer. The updating of the parameter continues until the number of margin hits has been minimized.
    Type: Grant
    Filed: January 14, 2014
    Date of Patent: February 9, 2016
    Assignee: Broadcom Corporation
    Inventors: Andrew Lin, Faramarz Bahmani

  • Systems, circuits and methods for adapting taps of a decision feedback equalizer in a receiver
    Patent number: 8416846
    Abstract: A receiver is optimized by adapting the taps of a decision feedback equalizer component within the receiver. Data decisions and error decisions are generated. These data decision and error decisions are used to derive an error rate of data by measuring the number of margin hits that occur. A balance value is also calculated from the data decisions and the error decisions. The balance value is used to update a tap of the decision feedback equalizer. The updating of the tap continues until the number of margin hits has been minimized.

  • Systems, circuits and methods for adapting parameters of components in a receiver
    Patent number: 8401064
    Abstract: A receiver is optimized by adapting parameters of components within the receiver. Various component parameters are adapted by using either a least means squared algorithm or a steepest descent algorithm. The taps of a decision feedback equalizer can be adapted by using either a least means squared algorithm or a steepest descent algorithm. The gain value of a linear equalizer and the input of a digital to analog converter coupled to the linear equalizer are also adapted through the least means squared algorithm or a steepest descent algorithm. A variable gain amplifier is also capable of being adapted through the use of the least means squared algorithm. Clock offsets are also configured by use of a steepest descent algorithm.
