Patents by Inventor Wissam Yussef Sabri EYSSA

Wissam Yussef Sabri EYSSA 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).

  • Trans-impedance amplifier for high speed optical-electrical interfaces
    Patent number: 8981853
    Abstract: A differential or pseudo-differential TIA includes an auxiliary differential amplifier input transistor pair cross-coupled to the output nodes to cancel undesired output signal components. The advantages of a classical differential topology are retained while performance at a high data rate is significantly improved.
    Type: Grant
    Filed: April 23, 2013
    Date of Patent: March 17, 2015
    Assignee: STMicroelectronics S.R.L.
    Inventors: Wissam Yussef Sabri Eyssa, Enrico Stefano Temporiti Milani, Daniele Baldi
  • Trans-impedance amplifier for high speed optical-electrical interfaces
    Patent number: 8907729
    Abstract: The differential trans-impedance amplifier uses trans-resistance(s) connected between the input nodes of a first differential amplifier, to implement a trans-impedance differential amplifier in a differential fashion and has two identical resistances, each connected between the photodiode and a respective DC voltage rail of a common bias network of the photodiode adapted to reverse bias the photodiode. The biasing resistances may be much larger than the trans-resistance(s) to prevent drawing any significant signal current from the photodiode. The amplifier may retain the advantages of a classical differential topology while effectively overcoming drawbacks that arise in high data rate applications.
