    • Electronic structure of low dimensional semiconductor systems 

      Gülseren, Oğuz (Bilkent University, 1992)
      Recent progress made in the growth techniques has led to the fabrication of the artificial semiconductor systems of lower dimension. Electrons and holes in these materials have quantization different from those of the ...
    • Gain variation and noise figure degradation in balanced amplifiers 

      Coşkun, Akif Alperen (Bilkent University, 2017-07)
      Although using balanced amplifiers in modern wireless communication systems has many advantages, the output and the noise response of the balanced ampli- fiers may vary from the expected value considerably due to the ...
    • Noise figure degradation in balanced amplifiers 

      Coskun, A. A.; Atalar, Abdullah (Institute of Electrical and Electronics Engineers Inc., 2017)
      Balanced amplifiers suffer from the noise figure performance in comparison with a stand-alone amplifier even with an ideal input divider. The noise parameters degrade further with an imperfect divider. We present exact and ...
