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.


  • Tugce Yazicigil won Second place at the Bell Labs Future X Days Student Research Competition with her research on "Enabling Cognitive Radio Systems with Compressed-Sampling Rapid Spectrum Sensors." Only 10 students were invited to present their innovative research at Bell Labs out of 50 applicants. Congratulations Tugce! SEAS Website (pdf)
