Research

Research Interests

Our research activities are generally focused on the design and implementation of Millimeter-Wave (MMW) and Radio Frequency (RF) Integrated Circuits and Systems in CMOS technology for a wide array of applications, including communication systems, automotive radar, and biomedical imaging. Silicon CMOS technology offers the highest level of integration as well as the lowest cost of fabrication of all semiconductor technologies. However, the losses introduced at high frequencies because of the low resistivity of silicon substrates makes the design of RF circuits very challenging. Our research is aimed at tackling these challenges by introducing new MMW/RF device and circuit techniques. Particularly, we have been actively working on the implementation of passive MMW/RF components such as inductors, capacitors, and resistors using active circuits that consist of a limited number of CMOS transistors. These active circuits occupy very small chip areas, offer high quality factors (less energy loss), and can be tuned to operate in different frequency ranges.

Current Research

We are currently working on the following research projects:

  • Active circuit implementation of passive MMW/RF components
  • Ultra wideband technology for communication, automotive and biomedical applications
  • 60 GHz short-range wireless networking
  • Development of dielectric models of deice fluids for time-domain reflectometry
