    • Designing circular CMUT cells using CMUT biasing chart 

      Köymen, Hayrettin; Atalar, Abdullah; Oğuz, H. Kağan (IEEE, 2012-10)
      A very accurate equivalent circuit model for circular CMUT cell is recently proposed. As a consequence of this model, the operating characteristics of the cell is derived and presented as a biasing chart for CMUTs. We ...
    • Electrically unbiased driven airborne capacitive micromachined ultrasonic transducer design 

      Ünlügedik, Aslı; Atalar, Abdullah; Kocabaş, Coşkun; Oğuz, H. Kağan; Köymen, Hayrettin (IEEE, 2012)
      We present a design method for airborne capacitive micromachined ultrasonic transducers (CMUT). We use an equivalent lumped element circuit to model both electrical and mechanical properties of CMUT and analyze it in ...
    • Nonlinear equivalent circuit model for circular CMUTs in uncollapsed and collapsed mode 

      Aydoğdu, Elif; Özgürlük, Alper; Oğuz, H. Kağan; Atalar, Abdullah; Kocabaş, Coşkun; Köymen, Hayrettin (IEEE, 2012)
      An equivalent electrical circuit model valid for collapsed mode operation of CMUT is described. The across and through variables of the circuit model are chosen to be rms force and rms displacement over the surface of the ...
    • A novel equivalent circuit model for CMUTs 

      Oğuz, H. Kağan; Olcum, Selim; Senlik, Muhammed N.; Atalar, Abdullah; Köymen, Hayrettin (IEEE, 2009-09)
      A nonlinear equivalent circuit for immersed transmitting capacitive micromachined ultrasonic transducers (CMUTs) is presented. The velocity profile across the CMUT surface maintains the same form over a wide frequency ...
