This paper presents an efficient way to compute the approximate time domain signal waveforms for RLCK circuits that have nontree or tree-like structures. The new method is based on a graph based approach to drive transfer function of any linear circuits. Our contribution is the introduction of Hurwitz approximation to the truncated transfer functions to enforce the stability of reduced systems....

The characteristics of dielectric backed planar conducting layers of arbitrarily shaped in a rectangular waveguide are calculated by means of coupled integral equation technique (CIET) which accurately takes higher order mode interactions. Equivalent structures for the accurate analysis whole structure are introduced in which magnetic surface currents are identified as the unknowns at the apert...

Synchronization phenomena in complex systems are important to describe various higher-dimensional nonlinear phenomena in the field of natural science. Studies on synchronization phenomena of coupled oscillators are extensively carried out in various fields; physics, biology, engineering and so on [1][4]. Because many researchers suggest that synchronization phenomena of coupled oscillators have...

This paper reports result of calculation and experimental realization of an electromechanical system that consists of a high-Q mechanical oscillator parametrically coupled in the manner of a capacitive transducer with a radio frequency (RF) circuit, which is in turn inductively coupled with another RF circuit. The system operates in the resolved sideband regime when the mechanical oscillator's ...

This article explores the main tradeoffs in design of subthreshold source-couple logic (STSCL) circuits. It is shown analytically that the bias current of each STSCL gate can be reduced to few pico-amperes with a reliable logic operation. Measurements on different digital building blocks are provided to validate the main concepts presented in this paper. Implemented in conventional 0.18μm CMOS ...

The accurate estimate of values of electromagnetic parameters are essential to determine the final circuit speeds and functionality for designing of high-performance integrated circuits and integrated circuits packaging. In this paper, the quasi-TEM analyses of symmetrical triple coupled Coplanar Waveguide (CPW) transmission lines and multilayer CPW broadside coupled-line balun are successfully...

Chua’s circuit is a simple electronic circuit exhibiting a wide variety of bifurcation and chaotic phenomena. Because of its universality and simplicity, Chua’s circuit has captured much interest among researchers in science and engineering. The circuit equations are described by the following set of differential equations: C1 dVC1 dt = 1 R (VC2 − VC1) − F (VC1) , C2 dVC2 dt = 1 R (VC1 − VC2) +...
