He has made significant contributions to the field of optical technology, particularly in the development of trans-impedance amplifiers. With a total of 2 patents to his name, Sukumaran continues to push the boundaries of innovation in his field.

Latest Patents

Sukumaran's latest patents focus on the control of linear trans-impedance amplifiers (TIAs) during the settling process after recovering from a loss of signal in receivers. One of his patents describes an optical device that includes a photodiode configured to receive optical signals and a linear TIA with a variable gain amplifier (VGA). This device features an automatic gain control loop that rectifies the output of the VGA and compares it with a threshold gain setting to generate an automatic gain control voltage. The detection circuitry is designed to detect changes in this voltage and disable the output stage of the linear TIA when no optical signals are present.

Another patent by Sukumaran details an optical receiver that comprises a photodiode, a TIA, a slope detection circuit, and a logic circuit. The TIA is coupled to the photodiode and includes an output stage and a feedback amplifier. The slope detection circuit monitors the feedback signal and provides a slope-status signal when a slope is detected. The logic circuit then squelches the output stage of the TIA in response to this signal, enhancing the receiver's performance.
