Bio
Dr. Tejasvi Das is an Associate Professor in the Department of Electrical and Microelectronic Engineering at RIT and director of the RF/Analog/Mixed-Signal Lab (RAMLab). Prior to joining academia, he spent 15 years in the semiconductor industry, where he held several R&D leadership roles, most recently as an IC Architect at Cirrus Logic. His has led the development of numerous high-volume IC products, and he has been granted over 180 U.S. and international patents spanning analog and mixed-signal IC design, including IoT sensing, adaptive circuits, audio systems, interference robustness, self-calibration, and signal-processing algorithms.
Dr. Das received his Ph.D. from RIT under the supervision of Dr. P. R. Mukund and is an alumnus of the university. His work has been recognized with multiple best paper awards, and he serves as a member of the IEEE Analog Signal Processing Technical Committee.
At RIT, Dr. Das leads research in high-performance RF, analog, and mixed-signal integrated circuits and systems, with emphasis on neuromorphic computing, hardware security, biosensing systems, and emerging device technologies. His group pursues cross-layer approaches spanning devices, circuits, systems and experimentally validated silicon prototypes for next-generation sensing, computing, and intelligent electronic systems.
Dr. Das teaches undergraduate and graduate courses in analog and mixed-signal IC design and is actively recruiting highly motivated B.S., M.S., and Ph.D. students for research positions in RAMLab.
