    • A 1 V CMOS programmable accurate charge pump with wide output voltage range 

      Tsitouras, A.; Plessas, F.; Birbas, M.; Kalivas, G. (2011)
      A 1 V, programmable, accurate, high speed, single-ended charge pump is proposed, suitable for low voltage PLLs. It is designed in TSMC 90-nm digital CMOS process and it consists of four switches in a current steering ...

    • 5-GHz fully differential multifunctional circuit 

      Plessas, F.; Tsitouras, A.; Kalivas, G. (2012)
      This letter presents a multifunctional circuit realising the functions of oscillation, frequency multiplication and frequency division at 5-GHz. A theoretical and experimental description of the circuit is given. The ...

    • Eating habits and factors affecting food choice of adolescents living in rural areas 

      Bargiota, A.; Delizona, M.; Tsitouras, A.; Koukoulis, G. N. (2013)
      OBJECTIVE: To establish factors that affect food choices among adolescents living in rural areas and to identify their food choices. DESIGN: A random sample of adolescents living in a Greek rural area (n=382) aged 12-18 ...

    • A linear, ultra wideband, low-power, 2.1-5 GHz, VCO 

      Tsitouras, A.; Plessas, F.; Kalivas, G. (2011)
      A linear, Ultra Wideband, low-power VCO, suitable for UWB-FM applications is proposed, forming the main part of a UWB-FM transmitter. The VCO is designed in TSMC 90 nm digital CMOS process and includes a Source-Coupled ...

    • Phase noise characterization of subharmonic injection locked oscillators 

      Plessas, F.; Tsitouras, A.; Kalivas, G. (2011)
      In this work we present a detailed study of the phase noise of subharmonic injection locked oscillators (s-ILOs). A new simple and efficient model has been presented for accurately predicting the phase noise of a microwave ...

    • Satellite Visible-Near Infrared Reflectance Correlates to Soil Nitrogen and Carbon Content in Three Fields of the Thessaly Plain (Greece) 

      Stamatiadis, S.; Evangelou, L.; Blanta, A.; Tsadilas, C.; Tsitouras, A.; Chroni, C.; Christophides, C.; Tsantila, E.; Samaras, V.; Dalezios, N.; Dimogiannis, D. (2013)
      Surface visible-near infrared (NIR) reflectance of bare soil by remote sensing devices has been used to infer topsoil properties such as organic matter, soil texture, water content, salinity, and crop residue cover. Spectral ...

    • A sub-1V supply CMOS voltage reference generator 

      Tsitouras, A.; Plessas, F.; Birbas, M.; Kikidis, J.; Kalivas, G. (2012)
      An integrated sub-1V voltage reference generator, designed in standard 90-nm CMOS technology, is presented in this paper. The proposed voltage reference circuit consists of a conventional bandgap core based on the use of ...
