Abstract—In this study, a complex behavior in two coupled chaotic circuits related with intermittency is investigated. When each chaotic circuit generates intermittency chaos near the three-periodic window, three different synchronization states appear and disappear in a chaotic manner. This complex behavior is modeled by a first-order Markov chain with four states. Further, the phenomenon is c...

Hassan Khalil’s research results and beautifully written textbook on nonlinear systems have influenced generations of researchers, including the authors of this paper. Using nonlinear systems techniques, this paper analyzes ring oscillator and cross-coupled oscillator circuits, which are essential building blocks in digital systems. The paper first investigates local and global stability proper...

In this study, synchronization state of the coupled chaotic circuits is investigated when a sinusoidal input signal is added by both of computer simulations and circuit experiments. It is confirmed that the synchronization state changes by the values of the amplitude and the angular frequency of the input signal.

A very low power mixed-signal design methodology based on subthreshold sourcecoupled circuits is presented, and a nano-Watt range analog-to-digital converter (ADC) circuit based on folding-interpolating topology is proposed as a complete design example. To reduce the power dissipation to sub-μW level, subthreshold source-coupled circuit family has been developed for both analog and digital part...

iran is a rather wide country, and, as a rule, the chrage per one call in s. t .d . (subscriber trunk dialing ) is required more compared with a local call , so, just after the opening of the std service widely in national telephone network, unconcerned use of the s. t. d. service has been caused on an incon- ceivable increase in telephone charge of th subscriber. this is a common problem for a...

Among the emerging technologies Field-Coupled devices like Quantum dot Cellular Automata are one of the most interesting. Of all the practical implementations of this principle NanoMagnet Logic shows many important features, such like a very low power consumption and the feasibility with up-to-date technology. However its working principle, based on the interaction among neighbor cells, is quit...

   In this paper we implement a simple DC model for CNTFETs already proposed by us in order to carry out static analysis of basic digital circuits. To verify the validity of the obtained results, they are compared with those of Wong model, resulting in good agreement, but obtaining a lighter ensuring compile and shorter execution time, which are the main character...

the types of transmission systems which today are available for long distance transmission of large numbers of telephone circuits are those for coaxial cables and radio links. the number of circuits is increased in both cases in step with development in technique. radio links have for several years been able to transmit 600 telephone circuits per system. and are now being designed for 960 circu...

Neuroscience research has examined separately how we detect human agents on the basis of their face and body (person perception) and how we reason about their thoughts, traits or intentions (person knowledge). Neuroanatomically distinct networks have been associated with person perception and person knowledge, but it remains unknown how multiple features of a person (e.g. thin and kind) are lin...

Today, the use of CMOS technology for the manufacture of electronic ICs has faced many limitations. Many alternatives to CMOS technology are offered and made every day. Quantum-dot cellular automata (QCA) is one of the most widely used. QCA gates and circuits have many advantages including small size, low power consumption and high speed. On the other hand, using special digital gates called re...
