Keynote: Simulating Acoustic Waveguides and MEMS Resonators for CMOS Technologies
The number of internet of things (IoT) connected and sub-GHz devices — such as industrial applications, home automation systems, and wearable technology — are growing by the billions each year. Therefore, the need for high-quality, low-cost resonators, which allow these devices to function properly, is more important than ever.
In this archived keynote talk from COMSOL Day: Electronic Devices, Bichoy Bahr of Texas Instruments (TI) introduces a type of resonator that is designed to keep up with the demands of the fast-paced technology industry. During the presentation, Bahr discusses how he uses simulation to analyze the structure and operating principles of this resonator, which he describes as a truly solid-state, monolithically integrated GHz complementary metal–oxide–semiconductor (CMOS)–MEMS resonator that relies on acoustic waveguides.
Bichoy Bahr received his PhD from the Massachusetts Institute of Technology in 2016. That same year, he joined TI's Kilby Labs, where he was later elected for TI's prestigious Tech Ladder group as technical staff (MGTS) in 2019. His research interests include MEMS resonators, phononic crystals, oscillators and timing circuits, ultrasonic transducers, and numerical optimization.
