Welcome to the homepage of the Kinget Group at Columbia University in New York City. Our research group is part of the Columbia Integrated Systems Laboratory in the Electrical Engineering Department.

Our research focuses on the design, simulation and measurement of

Our ongoing research projects are described in the "Research" section. You can find microphotographs of some of the chips we have designed in the "Chip Gallery". You can find our conference and journal papers listed in the "Publications" section. Our papers regularly appear in the IEEExplore Top 100 download ranking and the JSSC Most Read Articles lists.

  • The "Ultrasonic Wireless Sensors" team, Kshitij Yadav, John Kymissis and Peter Kinget, won the $100K First Prize in the Interdigital Innovation Challenge (pdf). The winners were announced on 21st September 2012 at the GigaOM's Mobilize conference held in San Francisco. The competition drew entries from top universities all across the United States and Canada, and consisted of a written proposal submission round followed by an incubation-phase round in which the teams were interviewed and submitted a final proposal. The ultrasonic wireless technology can extend the battery life of wireless sensor nodes by more than an order-of-magnitude. The team has built a custom integrated circuit to demonstrate the ultra-low power operation of this technology. It has further field-tested proof-of-concept ultrasonic communication modules and a demo video is available.
