  • MOS switched-current biquadratic filters

    Creator:
    Lee, Bor
    Abstract:
    A MOS biquadratic (biquad) filter employing the switched-current technique is reported. The circuit uses current-mode processing which can offer wide bandwidth, low voltage operation, and can be implemented with standard CMOS technology. Examples of lowpass, highpass, and bandpass filters are given which illustrate the synthesis procedures and the versatility of...

    Yindeepol, Wipawan, 1960-
    Abstract:
    Split and normal gate A1GaAs /GaAs MODFETs were fabricated along with the ohmic test structures and the Hall bar geometries. The DC characteristics of normal gate transistors were evaluated at room temperature and at 77K and the threshold voltages were extracted from the measurements and compared to the theoretical results....

  • Analysis and modeling of electrically long MESFETS and coupled schottky lines

    Creator:
    Mohammed, Ahmed Sarhan
    Abstract:
    The properties of linear active coupled lines consisting of electrically long GaAs MESFET structures are investigated for possible applications as traveling-wave broad-band amplifiers. In addition, the nonlinear coupled Schottky lines are studied for applications as voltage tunable circuit elements. The analysis of the general active asymmetric coupled transmission lines in...
