ECS Seminar - Bal Govind - Friday Noon 5/9 at PH233

Abstract:

CMOS microwave electronics is the workhorse of the wireless communications industry. Traditionally, the RF design community has pushed the boundaries of performance—such as signal integrity, noise suppression, and linearity—through increasingly complicated architectures, mainly to build better transceivers. In this seminar, we will take a step back and explore how the existing foundry stack could be repurposed to design a new style of high-speed analog computation. Severe nonlinearity in CMOS, typically considered a liability, could become an asset—enabling a new frequency-domain computation paradigm rather than the traditional time-domain computation used by digital processors, which are bottlenecked by clock speeds. Through our experiments on chips designed at Cornell, we believe we have identified a new class of AI inference accelerators that distinguish themselves from current analog and photonic technologies, offering instantaneous, broadband, and parametrically reconfigurable processing.


Bio:
Bal is a fourth-year PhD student in Electrical and Computer Engineering at Cornell University. Prior to Cornell, he received his master’s degrees in Electrical Engineering and Mechanical Engineering from North Carolina State University. His research has pivoted from acoustics and ultrasonic MEMS to high-speed microwave electronics. His recent work in CMOS integrated circuits has produced unconventional chip designs for 6G communications and analog computation.
