Bio
An engineer and inventor, Dr. Tejasvi Das spent 15 years in the semiconductor industry before joining RIT as an Associate Professor in January 2023. He has been granted over 160 US and International patents across a broad range of areas in the Analog & Mixed-signal IC domain, such as IoT sensing, interference robustness, haptics, audio processing, self-calibration, adaptive circuits and back-end algorithms. His inventions have been instrumental in the commercial success of numerous high-volume IC products. Dr. Das has held various R&D leadership positions in industry, ending as IC Architect at Cirrus Logic. He has successfully led multiple new technology initiatives from early proof of concept to volume production.
Dr. Das is the director of RAMLab at RIT. His research interests lie in high-performance, high-efficiency RF, Analog and Mixed-signal (RAM) circuits & systems, with particular focus on: IoT & bio sensing, Neuromorphic AI, Analog Computing, HW Security and dynamically adaptive mixed-signal systems. He is also very keen on exploring design methodologies for new and upcoming CMOS-compatible and post-CMOS devices.
He currently teaches undergraduate and graduate-level courses in Analog and Mixed-signal IC design.
Dr. Das is currently looking for highly motivated B.S./M.S./Ph.D. students for funded positions for his group at RAMLab.
