    CMOS Realization of All-Positive Pinched Hysteresis Loops
    (2017-08-06) Maundy, B. J.; Elwakil, A. S.; Psychalinos, C.
    Two novel nonlinear circuits that exhibit an all-positive pinched hysteresis loop are proposed. These circuits employ two NMOS transistors, one of which operates in its triode region, in addition to two first-order filter sections. We show the equivalency to a charge-controlled resistance (memristance) in a decremental state via detailed analysis. Simulation and experimental results verify the proposed theory.

    Fractional-Order Two-Port Networks
    (2016-06-09) Fouda, M. E.; Elwakil, A. S.; Radwan, A. G.; Maundy, B. J.
    We introduce the concept of fractional-order two-port networks with particular focus on impedance and admittance parameters. We show how to transform a impedance matrix with fractional-order impedance elements into an equivalent matrix with all elements represented by integer-order impedances; yet the matrix rose to a fractional-order power. Some examples are given.
