A Simple Current-Mode Quadrature Oscillator Using Single CDTA
(Společnost pro radioelektronické inženýrství, 2008-12)
This article presents a simple current-mode quadrature oscillator using a single Current Differencing Transconductance Amplifier (CDTA) as the active element. The oscillation condition and oscillation frequency can be ...
Comments on Pinched Hysteresis Loops of Memristive Elements
(Společnost pro radioelektronické inženýrství, 2015-12)
The hysteresis loops pinched in the v-i origin belong to well-known fingerprints of memristive elements driven by bipolar periodical signals. Some element properties follow from the loop behavior in the close neighborhood ...
Utilization of Euler-Lagrange Equations in Circuits with Memory Elements
(Společnost pro radioelektronické inženýrství, 2016-12)
It is well known that the equation of motion of a system can be set up using the Lagrangian and the dissipation function, which describe the conservative and dissipative parts of the system. However, this procedure, ...
High Input Impedance Voltage-Mode Biquad Filter Using VD-DIBAs
(Společnost pro radioelektronické inženýrství, 2014-09)
This paper deals with a single-input multiple-output biquadratic filter providing three functions (low-pass, high-pass and band-pass) based on voltage differencing differential input buffered amplifier (VD-DIBA). The quality ...
Time Domain Analysis of Linear Systems Using Laplace Inversion
(Společnost pro radioelektronické inženýrství, 1994-03)
An efficient method of time domain analysis of linear systems is proposed. This method is based on the state space approach and on the numerical Laplace inversion. The problems of the sampled-data input signal and steady-state ...
Four-Phase Oscillators Employing Two Active Elements
(Společnost pro radioelektronické inženýrství, 2011-04)
Two novel four-phase voltage-output oscillators are proposed. These circuits can also be utilized as quadrature oscillators with floating outputs. Each oscillator employs two DO-CIBA (Differential Output- Current Inverter ...
SPICE Model of Memristor with Nonlinear Dopant Drift
(Společnost pro radioelektronické inženýrství, 2009-06)
A mathematical model of the prototype of memristor, manufactured in 2008 in Hewlett-Packard Labs, is described in the paper. It is shown that the hitherto published approaches to the modeling of boundary conditions need ...
Multi-Step Numerical Laplace Inversion
(Společnost pro radioelektronické inženýrství, 1992-10)
An accurate numerical Laplace inversion algorithm is presented. In comparison with original multi-step inversion method, some improvements are made. The concrete Turbo Pascal routines are introduced.
Immediate Analysis of Periodic Steady States in Switched DC-DC Converters via SPICE
(Společnost pro radioelektronické inženýrství, 2012-04)
The method of immediate analysis of periodic steady states in switched DC-DC converters operating in the continuous current mode is described. The initial conditions, which correspond to the periodic steady state, are found ...
Differential Equations of Ideal Memristors
(Společnost pro radioelektronické inženýrství, 2015-06)
Ideal memristor is a resistor with a memory, which adds dynamics to its behavior. The most usual characteristics describing this dynamics are the constitutive relation (i.e. the relation between flux and charge), or ...
