Biography
Ji-Jon SIT has always been fascinated by feedback control and analog electronics. On writing this biography, he realized that his liberal arts education as a Yale Engineer could be credited for enabling his return to analog electronics for graduate studies despite doing his FYP on a digital microprocessor. At MIT he joined the Analog VLSI and Biological Systems Group under Rahul Sarpeshkar, and wrote his PhD dissertation on an analog architecture for neural stimulation of the cochlea, to aid in music perception for the deaf. This led to employment at Advanced Bionics in California as a Sr. RF and Systems engineer, where he worked from 2007-2015 on RFIC design, stimulation architecture, and telemetry systems in their latest cochlear implant. From 2015-2017 he joined a medical device startup which is still in stealth mode, but will soon release a platform neurotechnology with proven therapy for the treatment of disease at different sites in the body.
Research Interest
My current research interest is in near-field RF systems and design, for wireless power delivery and telemetry. In particular, I want to employ analog feedback control to optimize the efficiency of the wireless link, and am developing a closed-loop system in discrete electronics. The final solution however would be miniaturized into an RFIC.
