  • Accurate Empirical Fractional-Order Electrical Models of Young and Old Dentines 

    Herencsár, Norbert; Kartci, Aslihan; Cicekoglu, Oguzhan (IEEE, 2020-07-20)
    Electrical impedance spectroscopy (EIS) is a fast, non-invasive, and safe technique for bioimpedance measurement. In dental research, EIS has been used to detect tooth cracks and caries with higher accuracy than visual and ...
  • All-Pass Time Delay Circuit Magnitude Response Optimization Using Fractional-Order Capacitor 

    Herencsár, Norbert; Kartci, Aslihan; Tlelo-Cuautle, Esteban; Metin, Bilgin; Cicekoglu, Oguzhan (IEEE, 2018-08-05)
    Paper presents the integer- and fractional-order cases of a voltage-mode all-pass time delay circuit, or more frequently called as all-pass filter, employing a single negative-type current-controlled current inverting ...
  • A Comparative Study of Two Fractional-Order Equivalent Electrical Circuits for Modeling the Electrical Impedance of Dental Tissues 

    Herencsár, Norbert; Freeborn, Todd; Kartci, Aslihan; Cicekoglu, Oguzhan (MDPI, 2020-10-03)
    Background: Electrical impedance spectroscopy (EIS) is a fast, non-invasive, and safe approach for electrical impedance measurement of biomedical tissues. Applied to dental research, EIS has been used to detect tooth cracks ...
  • Memristor Emulator Applications Using the MOS-Only Technique 

    Metin, Bilgin; Herencsár, Norbert; Cicekoglu, Oguzhan (IEEE, 2018-08-05)
    The aim of this paper is to present a work towards a MOS transistor memristor emulator. The starting circuit employs an opamp, negative capacitors and loaded with a nonlinear resistor. The final aim is to design a memristor ...

    Herencsár, Norbert; Cicekoglu, Oguzhan; Šotner, Roman; Koton, Jaroslav; Vrba, Kamil (Springer, 2013-08-01)
    To increase the universality of the recently introduced voltage differencing inverting buffered amplifier (VDIBA), this letter presents a new voltage-mode (VM) multi-input–single-output (MISO) universal filter. The proposed ...
  • Transimpedance type MOS-C bandpass analog filter core circuits 

    Cevik, Ismail; Metin, Bilgin; Herencsár, Norbert; Cicekoglu, Oguzhan; Kuntman, Hakan (Springer Nature, 2021-02-10)
    In this paper, we present six area-efficient transimpedance type second-order analog filters. There are many applications where the available signal is current, however the necessary signal for further processing is voltage ...
