      A general purpose VLSI median filter and its applications for image processing 

      Karaman, Mustafa; Onural, Levent; Atalar, Abdullah (IEEE, 1989)
      A general-purpose median filter configuration consisting of two single-chip median filters is proposed. One of the chips is designed for applications requiring variable word-length and variable window size, whereas the ...

      A 128-bit microprocessor compatible programmable correlator chip for use in synchronous communication 

      Ungan, İ. Enis; Topçu, Satılmış; Atalar, Abdullah (IEEE, 1989)
      A single-chip microprocessor-compatible 128-b correlator is designed and implemented in a 3-μm M2CMOS process. Full-custom design techniques are applied to achieve the best tradeoff among chip size, speed, and power ...

      Design and implementation of a general purpose VLSI median filter unit and its applications 

      Karaman, Mustafa; Onural, Levent; Atalar, Abdullah (IEEE, 1989)
      A VLSI median filter unit has been designed and implemented in 3-μ m M2 CMOS, using full-custom VLSI design techniques. The unit consists of two single-chip median filters, one extensible and one real-time. The chips are ...

      A performance enhanced power divider structure 

      Taş, Vahdettin; Atalar, Abdullah (IEEE, 2014)
      We analyze the bandwidth capability of a divider with a series RLC circuit at the isolation arm. Analytical expressions for optimal component values are given. Bandwidth limiting effect of the pad capacitances of the chip ...

      Design considerations for MMIC distributed amplifiers 

      Ergun, Şanlı; Atalar, Abdullah (IEEE, 1994)
      The bandwidth of the input artificial line in a distributed amplifier is the main band limiting factor. By choosing this impedance properly the bandwidth of a distributed amplifier can be maximized. A four section GaAs ...

      Resonant harmonic response in tapping-mode atomic force microscopy 

      Sahin, O.; Quate, C. F.; Solgaard, O.; Atalar, Abdullah (American Physical Society, 2004)
      Higher harmonics in tapping-mode atomic force microscopy offers the potential for imaging and sensing material properties at the nanoscale. The signal level at a given harmonic of the fundamental mode can be enhanced if ...

      Using phase relations in microstrip directional couplers to achieve high directivity 

      Tas, V.; Atalar, Abdullah (2013)
      We analyze the microstrip directional couplers with a special focus on the phase difference between the coupled and isolated ports. The analysis uses the even-odd mode decomposition technique and network theory. The results ...

      Hybrid atomic force/scanning tunneling lithography 

      Wilder, K.; Soh, H. T.; Atalar, Abdullah; Quate, C. F. (American Vacuum Society, 1997)
      We present a new technique for performing lithography with scanning probes that has several advantages over standard methods. This hybrid lithography system combines the key features of the atomic force microscope (AFM) ...

      Two-dimensional micromechanical bimorph arrays for detection of thermal radiation 

      Manalis, S. R.; Minne, S. C.; Quate, C. F.; Yaralioglu, G. G.; Atalar, Abdullah (American Institute of Physics, 1997-06-16)
      We demonstrate that two-dimensional arrays of micromechanical bimorphs can be used as thermal sensors to image infrared (IR) radiation. A density of 100 pixels per mm2 is achieved by coiling a bimorph beam into the shape ...

      Analytic modeling of loss and cross-coupling in capacitive micromachined ultrasonic transducers 

      Bozkurt, A.; Degertekin, F. L.; Atalar, Abdullah; Khuri-Yakub, B. T. (IEEE, Piscataway, NJ, United States, 1998)
      The structural loss mechanism of capacitive micromachined ultrasonic transducer (cMUT) is investigated using finite element analysis and the normal mode theory. A single micromachined transducer membrane on an infinite ...
