Welcome to the VLSI Research Group
The VLSI Research Laboratory at the University of Minnesota focuses on developing core circuit technologies for enabling smart and energy-efficient integrated systems. Applications we target range from internet-of-things, neuromoprhic computing, microprocessors, portable computing, sensor networks, medical devices, radiation hardened integrated circuits, to beyond CMOS computing. Our group's research frequently appears in top publications such as ISSCC, IEDM, VLSI, CICC, IRPS, and JSSC.
