Electrical and Computer Engineering

Carlos Saavedra, P.Eng.

Biographical Sketch

Carlos Saavedra received the B.Sc. degree from the University of Virginia* in 1993 and the Ph.D. degree from Cornell University in 1998, both in electrical engineering.

From 1998 to 2000 he was a Senior Enginer at Millitech Corporation in Massachusetts where he designed front-end transceiver modules for 28 GHz and 38 GHz broadband communications systems. In 2000 he joined the faculty of Queen's University at Kingston where he now holds the rank of Professor. He served as Graduate Chair of the Department of Electrical and Computer Engineering (ECE) from 2007 to 2010.

Prof. Saavedra is Associate Editor of the IEEE Transactions on Microwave Theory and Techniques, is Section Chair of the NSERC Discovery Grants Evaluation Group 1510 (ECE) and is a member of the technical program committee (TPC) of the IEEE International Microwave Symposium (IMS). He served as Chair of the IEEE MTT-S Technical Coordinating Committee on Signal Generation and Frequency Conversion and was Guest Editor of the September 2013 Focus Issue of the IEEE Microwave Magazine on the 100 Years of Mixer Technology. He was on the Steering Committee of the 2012 IEEE IMS (Montreal) and was on the TPC of the IEEE RFIC Symposium from 2008 to 2011. Prof. Saavedra is a Senior Member of the IEEE and is a registered professional engineer (P. Eng.) in the province of Ontario, Canada.

Research Interests

  • Gigahertz-range integrated circuits
  • Mixers and frequency multipliers
  • Distortion cancellation and linearization techniques
  • Microwave operational transconductance amplifiers
  • Harmonic oscillators and self-oscillating mixers
  • Ultrabroadband circuits for impulse radio communications and radar

An important research thrust in my research group is in the area of broadband, low-noise, frequency mixers. These are non-linear circuits that perform the critical role of modulating a carrier frequency with either digital or analog information and furthermore they can be used to move spectral energy content from one frequency band to another to enable very long-distance information transfer between a transmitter and a receiver. Mixers are also found extensively in scientific instrumentation. We also have significant activities in gigahertz-range operational transconductance amplifiers (OTA's). Using OTA's as circuit building blocks we have demonstrated novel phase shifters, active circulators and attenuators that have low dc power consumption and are exceptionally compact in size. For ultra wideband radar systems we are investigating new pulse generation and amplification circuits. Further information about our research work can be found at my research website:
