The DC analysis and transient analysis parts of the general electrical circuit analysis program ESACAP are parallelized to run on the Intel iPSC. Most of the program runs unchanged on the cube manager. Only the solution of the systems of nonlinear algebraic equations is parallelized to run on the hypercube parallel computer. The nonlinear equations arise either from the DC problem or from the d...

the rapid scaling in modern cmos technology has motivated the researchers to design new analog-to-digital converter (adc) architectures that can properly work in lower supply voltage. an exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. this paper is going to review the recent development in t...

We investigate the results of recently published experiments on the quantum behavior of Josephson circuits in terms of the classical modelling based on the resistively and capacitivelyshunted (RCSJ) junction model. Our analysis shows evidence for a close analogy between the nonlinear behavior of a pulsed microwave-driven Josephson junction at low temperature and low dissipation and the experime...

A powerful and systematic approach to behavioral modeling of nonlinear microwave/RF circuits in the time domain is presented, integrating several techniques from nonlinear dynamical systems analysis. Algorithms based on information-theoretic principles help determine efficient tradeoffs between model accuracy, speed, and complexity. Models are constructed from large-signal microwave measurement...

A simple and efficient modified harmonic-balance technique is presented. This new algorithm is suitable for the large-signal time-dependent analysis of nonlinear millimeter wave circuits. The accurate design and successful implementation of very high frequency nonlinear circuits requires both a detailed understanding of the physical operation of the active devices and of how these nonlinear dev...

The nonlinear dynamics of chaotic circuits generate a rich spectrum of signals. This observation suggests that these circuits could potentially provide an implementation of a novel framework of computation. In support of this hypothesis, computational complexity of the nervous system is achieved in large part through the nonlinear elements of electrically excitable membranes. In this study, we ...

----Research in nonlinear dynamics and complexity has made remarkable progress in recent years. Almost all power electronic circuits exhibit some kind of nonlinear behavior e.g., quasi-periodicity, subharmonic oscillations, bifurcation, chaos. The aim of this paper is to investigate the nonlinear phenomenon and chaotic behavior in a DC-DC buck converter. The derivation of the discrete-time map ...

Being inspired by the recent studies of photonic crystal waveguides and circuits, we analyze nonlinear stationary modes localized in waveguide bends, in the framework of the discrete nonlinear Schrödinger equation for a planar geometry. We introduce a simple model of a waveguide bend and examine the interplay between discreteness, nonlinearity and geometry for the existence and stability of non...
