About

Graduate student pursuing MS in Electrical and Computer Engineering at The University of Texas at Austin, specializing in Power Management ICs and Analog IC Design. Currently working on advanced power converter designs using Cadence Virtuoso, with focus on high-efficiency DC-DC converters, control loop design, and integrated circuit optimization. Recent projects include a V² peak current-mode controlled synchronous buck converter using PMOS-NMOS switch combination achieving around 90% efficiency, and optimized two-stage operational transconductance amplifiers. Previously worked as an R&D Engineer at Tribi Systems, designing power electronics for automotive and residential applications, and as an Analog & Power Electronics Design Intern at the Indian Space Research Organization (ISRO), where I developed robust bus regulation systems for space applications. Technical expertise includes: - Power Electronics: DC-DC Converters, SMPS, Motor Control Drives - IC Design: Analog IC Design (OTA, Op-Amps), PMIC Design using Cadence Virtuoso - Power Switch Design: PMOS-NMOS synchronous topologies, switch segmentation - Simulation & Modeling: MATLAB/Simulink, SPICE, LTSpice - Embedded Systems: Motor control algorithms, data acquisition systems Published researcher at IEEE ICEPE 2023 on electromagnet-based wound field synchronous motor control drives. Open to opportunities in Power Electronics, Analog IC Design, and Power Management IC development.
