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.

In case you wonder: 'The electronic world is going digital, why analog?', check out these quotes.

If you are interested in research projects for undergraduate or M.S. students or in opportunities to join our group, check out the "Prospective Students" section.

  • Our group will present two papers at the 2013 IEEE Radio Frequency Integrated Circuits Symposium (RFIC). Jianxun will present "A DC-9.5GHz Noise-Canceling Distributed LNA in 65nm CMOS" and Teng Yang and Karthik Tripurari will present "A 0.5GHz-1.5GHz Order Scalable Harmonic Rejection Mixer." Congratulations Jianxun, Teng and Karthik.

  • Baradwaj Vigraham's work on ultra-low power wireless links that enable self-powered sensor nodes was featured in the PRESS. This research is part of the EnHANTs project.

  • Baradwaj Vigraham will present his research on "A Self-Duty-Cycled and Synchronized UWB Receiver SoC Consuming 375pJ/bit for -76.5dBm Sensitivity at 2Mbps" at the IEEE International Solid-State Circuits Conference (ISSCC) in San Francisco in February 2013 (paper 25.3). Congratulations Baradwaj!

  • Jayanth Kuppambatti will present a paper at the IEEE Custom Integrated Circuits Conference (CICC) 2012 entitled "A Current Reference Pre-charged Zero-crossing Pipeline-SAR ADC in 65nm CMOS." Congratulations Jayanth!

  • 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.
