Research @ LRF

The focus of our research is  the development of sensors, circuits and  systems for applications requiring measurement. Due to our strong background in RF design, we give more emphasis on wireless or contactless solutions. Depending on the necessity, we design CMOS integrated circuits for miniaturization and low power consumption.
In addition, we are very committed to the academic excellence and social  relevance of the research. We prioritize high impact factor journals, such as IEEE Transactions. for communicating  our results.
Next, we detail the LRF expertise by areas of interest:

  • RF electronics (Integrated and discrete): we designed discrete and integrated RF circuit blocks for transceivers (900 MHz, 2.4 GHz), such as oscillators, LNAs, Power amplifiers and mixers.
  • Wireless EnergyTransfer:  we have been working on miniaturized power transfer systems, integrated in CMOS technology.
  • Contactless Measurement: we developed a method for the characterization of magnetically  coupled  resonators with no need of wires.
  • Chipless Sensing: we have been  developing passive sensors that can detect relative humidity and can be read without the need of physical contact.
  • Permitivity  Measurement: we developed a sensor based on a resonant cavity that can be applied to the measurement of  oil-water fraction in  petroleum exploration fields.   The same sensor has been applied to  monitoring  the relative amount of  solids and fat percentage  in bovine  milk.
