  • About v-i Pinched Hysteresis of Some Non-Memristive Systems 

    Biolek, Dalibor; Biolek, Zdeněk; Biolková, Viera; Ascoli, Alon; Tetzlaff, Ronald (Hindawi, 2018-09-24)
    A special subset of two-terminal elements providing pinched hysteresis loops in the voltage-current plane with the lobe area increasing with the frequency is analysed. These devices are identified as non-memristive systems ...
  • Analytical Computation of the Area of Pinched Hysteresis Loops of Ideal Mem-Elements 

    Biolek, Zdeněk; Biolek, Dalibor; Biolková, Viera (Společnost pro radioelektronické inženýrství, 2013-04)
    The memory elements, memristor being the best known of them, driven by a periodical waveform exhibit the well-known pinched hysteresis loops. The hysteresis is caused by a memory effect which results in a nonzero area ...
  • Behavioral Modeling of Memcapacitor 

    Biolek, Dalibor; Biolek, Zdeněk; Biolková, Viera (Společnost pro radioelektronické inženýrství, 2011-04)
    Two behavioral models of memcapacitor are developed and implemented in SPICE-compatible simulators. Both models are related to the charge-controlled memcapacitor, the capacitance of which is controlled by the amount of ...
  • Chaotic Dynamics of Modified Wien Bridge Oscillator with Fractional Order Memristor 

    Rajagopal, K.; Li, C.; Nazarimehr, F.; Karthikeyan, A.; Duraisamy, P.; Jafari, S. (Společnost pro radioelektronické inženýrství, 2019-04)
    In this paper a modified third order Wien bridge oscillator with fractional order memristor is proposed. Various dynamical properties of the proposed oscillator are investigated such as equilibrium points, Eigenvalues, ...
  • Duality of Complex Systems Built from Higher-Order Elements 

    Biolek, Dalibor; Biolek, Zdeněk; Biolková, Viera (Hindawi, 2018-09-07)
    The duality of nonlinear systems built from higher-order two-terminal Chua’s elements and independent voltage and current sources is analyzed. Two different approaches are now being generalized for circuits with higher-order ...
  • Fracmemristor chaotic oscillator with multistable and antimonotonicity properties 

    Lu, Haikong; Petržela, Jiří; Götthans, Tomáš; Rajagopal, Karthikeyan; Sajad, Jafari; Hussain, Iqtadar (Elsevier, 2020-06-17)
    Memristor is a non-linear circuit element in which voltage-current relationship is determined by the previous values of the voltage and current, generally the history of the circuit. The nonlinearity in this component can ...
  • Higher-Order Hamiltonian for Circuits with (alpha,beta) Elements 

    Biolek, Zdeněk; Biolek, Dalibor; Biolková, Viera; Kolka, Zdeněk (MDPI AG, 2020-04-05)
    The paper studies the construction of the Hamiltonian for circuits built from the (alpha,beta) elements of Chua’s periodic table. It starts from the Lagrange function, whose existence is limited to sigma-circuits, i.e., ...
  • Lagrangian for circuits with higher-order elements 

    Biolek, Zdeněk; Biolek, Dalibor; Biolková, Viera (MDPI, 2019-10-29)
    The necessary and sufficient conditions of the validity of Hamilton’s variational principle for circuits consisting of (alpha,beta) elements from Chua’s periodical table are derived. It is shown that the principle holds ...

    Yu, J.; Mu, X.; Xi, X.; Wang, S. (Společnost pro radioelektronické inženýrství, 2013-12)
    In this paper, we present a memristor model with piecewise window function, which is continuously differentiable and consists of three nonlinear pieces. By introducing two parameters, the shape of this window function can ...

    Biolek, Dalibor; Biolek, Zdeněk; Biolková, Viera; Kolka, Zdeněk (Společnost pro radioelektronické inženýrství, 2015-06)
    The paper refers to problems of modeling and computer simulation of generic memristors caused by the so-called window functions, namely the stick effect, nonconvergence, and finding fundamentally incorrect solutions. A ...

    Xu, K.D.; Li, X.S.; Guo, Y.J.; Liu, Q.H. (Společnost pro radioelektronické inženýrství, 2016-12)
    Simple current- and voltage-controlled memristive circuit macro-models using SPICE are proposed to capture the nonlinear hysteresis loop behaviors in this paper. Different current-voltage characteristics are investigated ...
  • SPICE model of memristive devices with threshold 

    Pershin, Y. V.; Di Ventra, M. (Společnost pro radioelektronické inženýrství, 2013-06)
    Although memristive devices with threshold voltages are the norm rather than the exception in experimentally realizable systems, their SPICE programming is not yet common. Here, we show how to implement such systems in the ...
