Krishna B. Thirunagari has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Receiver for performing adaptive equalization and method
    Patent number: 7539244
    Abstract: A receiver includes a filter capable of receiving an input signal and generating an output signal. The filter provides a transfer function. The filter includes a first stage capable of adjusting a pole and a first zero of the transfer function. The filter also includes a second stage capable of adjusting a second zero of the transfer function. In addition, the filter includes a third stage capable of adjusting a third zero of the transfer function.

  • Apparatus and method for performing impedance synthesis in a transmitter
    Patent number: 7486786
    Abstract: A method includes generating an output signal at a transmitter using an input signal. The method also includes providing the output signal for communication over a communication link. The method further includes identifying a return signal by at least partially removing from the output signal at least one of: the communicated signal and base line wander. In addition, the method includes establishing a synthesized impedance to the return signal.
