Patent number: 10748890Abstract: Disclosed herein is an electronic device including an IO node, with a receiver coupled to receive input from the IO node. A transmitter driver has a first n-channel DMOS with a source coupled to the IO node. A pass gate circuit decouples the IO node from the receiver based upon presence of a negative voltage at the IO node and couples the IO node to the receiver based upon lack of presence of the negative voltage at the IO node. A transmit protection circuit applies the negative voltage from the IO node to the gate and bulk of the first n-channel DMOS based upon the presence of the negative voltage at the IO node.Type: GrantFiled: March 31, 2017Date of Patent: August 18, 2020Assignee: STMicroelectronics International N.V.Inventor: Ravinder Kumar

Patent number: 10644703Abstract: A level shifting circuit receives a first input signal and complement of the first input signal as inputs and generates a level shifted first output signal and complement of the first output signal as outputs. The level shifting circuit includes a number of transistors that support body biasing. One set of body bias signals applied to certain ones of those transistors is generated as a function of the logical combination of the first input signal and the first output signal. Another set of body bias signals applied to certain other ones of those transistors is generated as a function of the logical combination of the complement of the first input signal and the complement of the first output signal. The conditional body bias applied to the transistors of the level shifting circuit makes the circuit operational for level shift at very low supply voltage levels.Type: GrantFiled: June 4, 2019Date of Patent: May 5, 2020Assignee: STMicroelectronics International N.V.Inventor: Ravinder Kumar

Patent number: 10604708Abstract: A multi-stage hydrotreating process obtains ultra-low sulfur diesel boiling range hydrocarbon having less than 10 ppm sulfur with elimination of external hot high pressure separator and avoids the formation of recombinant mercaptans by removing excess hydrogen sulfide formed during hydroprocessing reaction. The process includes mixing a diesel boiling range hydrocarbon feedstock with hydrogen and sending to the first predominantly liquid phase hydroprocessing reaction stage. Effluent from the first hydroprocessing reaction stage is sent to first separator zone of open and empty space in the upper part of the second hydroprocessing reaction stage to flash off the dissolved reaction products hydrogen sulfide and ammonia. Liquid part of the effluent of first hydroprocessing reaction stage is passed to the second predominantly liquid phase hydroprocessing reaction stage.Type: GrantFiled: March 5, 2018Date of Patent: March 31, 2020Assignee: INDIAN OIL CORPORATION LIMITEDInventors: Ganesh Vitthalrao Butley, Yamini Gupta, Mainak Sarkar, Arun Arangarasu, Madhusudan Sau, Brijesh Kumar, Santanam Rajagopal, Ravinder Kumar Malhotra
