نویسندگان
چکیده
Chaotic oscillators based on RC-elements and nonlinear amplifiers with sigmoid function only are discussed. The analysis of the structure a number of wellknown oscillators is carried out. On the basis of that analysis the structure of the oscillators which consist of RC–elements and op amps only and capable to show chaotic oscillations is suggested. Computer simulation of chaotic behavior of oscillators is carried out.

Rc Chaotic Oscillators
Recent investigations show that wireless communication systems are a very promising application area of chaotic dynamics. At the same time synthesis of chaotic oscillators suitable for IC implementation and producing chaotic oscillations in the specified frequency band is a problem. Here the problem of synthesis of RC chaotic oscillator with preassigned spectrum is discussed. Spectral propertie...
متن کاملAnticipating, complete and lag synchronizations in RC phase-shift network based coupled Chua's circuits without delay.
We construct a new RC phase shift network based Chua's circuit, which exhibits a period-doubling bifurcation route to chaos. Using coupled versions of such a phase-shift network based Chua's oscillators, we describe a new method for achieving complete synchronization (CS), approximate lag synchronization (LS), and approximate anticipating synchronization (AS) without delay or parameter mismatch...
متن کاملConstruction of Classes of Circuit-Independent Chaotic Oscillators Using Passive-Only Nonlinear Devices
Two generic classes of chaotic oscillators comprising four different configurations are constructed. The proposed structures are based on the simplest possible abstract models of generic second-order RC sinusoidal oscillators that satisfy the basic condition for oscillation and the frequency of oscillation formulas. By linking these sinusoidal oscillator engines to simple passive first-order or...
متن کاملPhase chaos in coupled oscillators.
A complex high-dimensional chaotic behavior, phase chaos, is found in the finite-dimensional Kuramoto model of coupled phase oscillators. This type of chaos is characterized by half of the spectrum of Lyapunov exponents being positive and the Lyapunov dimension equaling almost the total system dimension. Intriguingly, the strongest phase chaos occurs for intermediate-size ensembles. Phase chaos...
متن کاملAmplitude Death Induced by a Global Dynamic Coupling
This paper presents a dynamic connection that can induce amplitude death in globally coupled oscillators. A linear analysis clarifies a local stability condition for global amplitude death. The analysis also indicates that the odd-number property, which is known in delayed feedback control, exists in global dynamic coupled oscillators. Furthermore, global amplitude death is experimentally obser...
