    • AlGaN/GaN HEMT-based fully monolithic X-band low noise amplifier 

      Schwindt, R.; Kumar, V.; Aktas, O.; Lee, J. W.; Adesida, I. (Wiley, 2005-04)
      A fully monolithic AlGaN/GaN HEMT-based low noise amplifier is reported. The circuit demonstrated a noise figure of 3.5 dB, gain of -7.5 dB, input return loss of -7.5 dB, and output return loss of -15 dB at 8.5 GHz. The ...
    • Bandwidth improvement in a cMUT array with mixed sized elements 

      Bayram, Can; Olcum, Selim; Şenlik, Muhammed N.; Atalar, Abdullah (IEEE, 2005-09)
      A capacitive micromachined ultrasonic transducer (cMUT) is typically fabricated by concatenation of several cMUT cells with identical physical dimensions. If the membrane thickness is kept fixed, the radius of the cMUT ...
    • Design charts to maximize the gain-bandwidth product of capacitive micromachined ultrasonic transducers 

      Ölçüm, Selim; Şenlik, Muhammed Niyazi; Bayram, Can; Atalar, Abdullah (IEEE, 2005)
      In this work we define a performance measure for capacitive micromachined ultrasonic transducers (cMUT) in the form of a gain-bandwidth product to investigate the conditions that optimize the gain and bandwidth with respect ...
    • Integral action based Dirichlet boundary control of Burgers equation 

      Efe, M. Ö.; Özbay, Hitay (IEEE, 2003)
      Modeling and boundary control for Burgers Equation is studied in this paper. Modeling has been done via processing of numerical observations through singular value decomposition with Galerkin projection. This results in a ...
