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:

  • Wireless Power Transfer:  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.
  • RF electronics: we designed discrete and integrated RF circuit blocks for transceivers (900 MHz, 2.4 GHz), such as oscillators, LNAs, Power amplifiers and mixers.
  • Circuits for biomedical applications :  we designed discrete and integrated analog and mixed-signal circuits for biomedical applications such as variable-gain amplifiers, A/D converters, filters and transducers.
  • Wireless Body Area Networks: we have been studied the HBC channel and have been designing integrated circuits for a HBC transceiver.
  • SDR Radar Tecnologies: The Electronics Support Measures (ESM) systems are designed to intercept, classify and identify RF emitters through the passive monitoring of the electromagnetic environment. In parallel to this, since the introduction of Software-Defined Radio (SDR) approach, applications of different complexity, from FM broadcast receiving and recording to LTE spoofing and even space communications, have been developed. Furthermore, on recent years, tablet devices have arisen on human’s lives like one of the most convenient equipment ever, due to their portability, furtiveness and cheapness. This context suggests the possibility of development of SDR-based ESM systems and that is the challenge of our work
