Patents by Inventor Jeb M. Binkley

Jeb M. Binkley 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).

  • Publication number: 20220090963
    Abstract: A system for converting an optical signal into an electrical signal includes at least one differential Trans-Impedance Amplifier (TIA). To minimize (preferably eliminate) DC offset issues at the TIA output, an Input Counter-Offset (ICO) circuit is provided to remove the DC component of the initial optical signal from the input to the TIA. To further maximize the removal of DC offset at the TIA output, an Output Counter-Offset circuit is provided to take DC offset from the TIA output for use as a negative feedback directly to the input of the TIA. Modifications of the present invention are also intended for use with two TIA terminations and with a travelling wave photodiode.

  • Publication number: 20220094876
    Abstract: Circuitry for an optical receiver includes a photodiode for converting an optical signal into a photocurrent having an AC portion Ipd(AC) and a DC portion Ipd(DC). The circuitry includes a circuit element that is connected between the photodiode and the input to a Trans-Impedance Amplifier (TIA). Included in the circuit element is an AC bypass capacitor Cbp and a sensor. In detail, the sensor may be either a current sensor or a voltage sensor. In either case, the sensor establishes a cancellation current for removing the DC portion Ipd(DC) from the photocurrent while the AC bypass capacitor Cbp shunts an AC portion Ipd(AC) to ground. The result is that only an AC portion Ipd(AC) of the optical signal is maintained for input into the TIA.
