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 ...

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 ...

Hamilton’s principle for circuits with dissipative elements 

Biolek, Zdeněk; Biolek, Dalibor; Biolková, Viera (Hindawi, 2019-10-28)
The classic form of Hamilton’s variational principle does not hold for circuits with dissipative elements. It is shown in the paper that this may not be true in the case of systems consisting of the so-called higher-order ...

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 ...

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., ...

Design of the simple oscillator with linear tuning and pi/4 phase shift based on emulator of the modified current differencing unit 

Šotner, Roman; Jeřábek, Jan; Herencsár, Norbert; Vrba, Kamil (The Institute of Electronics, Information and Communication Engineers (IEICE), 2015-10-10)
This paper presents a simple oscillator with 45 degrees phase shift between output signals. A Modified current Differencing Unit (MCDU) was used for its design. The MCDU offers controllability of input resistances ...

Study of Small-signal Model of Simple CMOS Amplifier with Instability Compensation of Positive Feedback Loop 

Šotner, Roman; Jeřábek, Jan; Herencsár, Norbert; Vrba, Kamil; Lahiri, Abhirup; Dostál, Tomáš (De Gruyter Open, 2015-07-06)
The paper deals with precise analysis of simple AC variable gain CMOS amplifier. The circuit can be used as a simple voltage follower (6 MOS transistors are required) or amplifier. The main attention of this work is focused ...

Novel first-order all-pass filter applications of z-copy voltage differencing current conveyor 

Šotner, Roman; Herencsár, Norbert; Jeřábek, Jan; Vrba, Kamil; Dostál, Tomáš; Jaikla, Winai; Metin, Bilgin (NISCAIR ONLINE PERIODICALS REPOSITORY (NOPR), 2015-08-05)
The application of z-copy voltage differencing current conveyor (ZC-VDCC) in simple and interesting first-order all-pass sections has been studied in the present paper. The solutions presented here have presumptions for ...

New Resistorless and Electronically Tunable Realization of Dual-Output VM All-Pass Filter Using VDIBA 

Herencsár, Norbert; Minaei, Shahram; Koton, Jaroslav; Yuce, Erkan; Vrba, Kamil (Springer, 2013-01-07)
In this paper, a new active element called voltage differencing inverting buffered amplifier (VDIBA) is presented. Using single VDIBA and a capacitor, a new resistorless voltage-mode (VM) first-order all-pass filter (APF) ...

New resistorless tunable voltage-mode universal filter using single VDIBA 

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 ...
