      Microfabricated ultrasonic transducers: towards robust models and immersion devices 

      Ladabaum, I.; Jin, X.; Soh, H. T.; Pierre, F.; Atalar, Abdullah; Khuri-Yakub, B. T. (IEEE, 1996-11)
      The successful fabrication of ultrasonic immersion transducers is reported. Transducers are observed to operate from 1 MHz to 20 MHz in water, with the frequency range limited by electronics, not the transducers. Transmission ...

      A VLSI receive beamformer for digital ultrasound imaging 

      Karaman, Mustafa; Kolağasıoğlu, Ertuğrul; Atalar, Abdullah (IEEE, 1992-03)
      A VLSI architecture for real-time digital receive beamforming in phased array ultrasound imaging is proposed. The architecture is an inverse binary tree like structure with N stages where N is the number of array elements. ...

      Mic-in-CMOS: CMUT as a sealed-gap capacitive microphone 

      Köymen, Hayrettin; Ahiska, Y.; Atalar, Abdullah; Köymen, I.; Taşdelen, A .Sinan; Yılmaz, Mehmet (IEEE, 2020)
      The design and production of a CMOS compatible, watertight and ingress-proof CMUT (capacitive micromachined ultrasonic transducer) microphone, mic-in-CMOS, with vacuum-gap is described. We present an analytical ...

      Accurate and process-tolerant resistive load 

      Sütbaş, Batuhan; Özbay, Ekmel; Atalar, Abdullah (IEEE, 2020)
      Resistive terminations cannot preserve high-quality matching at high frequencies due to the parasitic effects of the nonideal resistor. Moreover, resistance values of the termination resistors in integrated circuits are ...

      High-Intensity airborne CMUT transmitter array with beam steering 

      Khan, Talha Masood; Taşdelen, Akif Sinan; Yılmaz, Mehmet; Atalar, Abdullah; Köymen, Hayrettin (IEEE, 2020)
      A 2×2 high-intensity CMUT transmit array that is capable of two-dimensional beam steering is presented. The device uses an ac drive voltage at half the ultrasound frequency without any dc bias, enabling the usage of the ...
