Nirmal Bissonauth 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).

  • Signal detection for GPON optical line terminal
    Patent number: 10972815
    Abstract: A signal detection circuit has a first differential amplifier including a first input coupled for receiving a data signal, and a second input coupled for receiving a threshold signal. A current steering circuit is coupled to an output of the first differential amplifier to establish a threshold for the first differential amplifier. A latch has an input coupled to the output of the first differential amplifier for latching a signal detect. A second amplifier has an input coupled to the output of the first differential amplifier and an output coupled to the input of the latch. A third amplifier has an input coupled to the output of the first differential amplifier and an output providing the data signal. The current steering circuit can be disabled which removes the need for the third amplifier as the data signal path is through second amplifier.
