Title: Subratakumar Mandal: Innovator in High-Speed I/O Technologies
Introduction
Subratakumar Mandal is a prominent inventor based in Portland, OR (US). He has made significant contributions to the field of high-speed I/O interconnect technologies. With a total of 5 patents to his name, Mandal's work focuses on improving system timing margins and eye width measurements in high-speed data transmission.
Latest Patents
Mandal's latest patents include a system for timing margin improvement of high-speed I/O interconnect links. This invention describes methods and apparatus for enhancing system timing margins by utilizing fine training of a phase interpolator. In some embodiments, the I/O links employ a forward clock architecture to transmit data from the transmit driver to the receiver logic. Additionally, at the receiver side, Phase Interpolator (PI) logic is used to position the sampling clock at the center of the valid data window or eye. An embodiment of this invention also features a Digital Eye Width Monitor (DEWM) logic that measures data eye width in real time. Another notable patent is the gated ring oscillator-based digital eye width monitor, which provides a novel system and method for measuring eye width in high-speed I/O applications. This DEWM system offers on-die capabilities to directly measure the left and right eye-width in picoseconds, achieving single-digit pico-second level accuracy.
