This work presents new frequency-domain methods for the analysis and simulation of circuits based on a nonlinear resonator, with operation ranges delimited by turning points. Insightful analytical conditions fulfilled at these points are derived, which will enable an identification effect each circuit element their location in solution curve. The cusp points, or co-dimension two bifurcations me...

The nullor is a theoretical two-port element suitable to model several multi-port devices common in audio circuitry, such as ideal operational amplifiers, transconductance and transistors operating linear regime. In this manuscript, we present an approach for the Wave Digital (WD) modeling implementation of circuits with multiple nullors. particular, propose compute scattering matrices WD topol...

due to the expected increase of defects in circuits based on deep submicron technologies, reliability has become an important design criterion. although different approaches have been developed to estimate reliability in digital circuits and some measuring concepts have been separately presented to reveal the quality of analog circuit reliability in the literature, there is a gap to estimate re...

After the fabrication of several devices showing memristive switching behavior, recently a growing interest to the realization of dynamical nonlinear circuits based on memristors has been manifested. Currently, many memristor circuits have been mostly conceived on the basis of theoretical memristor models. However, in order to analyze the dynamical behavior of memristor circuits with real compo...

It is shown that, through an extension of the describing function technique and of Loeb's stability criterion, the number and the characteristics of the periodic attractors occurring in one-dimensional arrays of coupled Chua's circuits can be accurately predicted. The technique can also be applied to the investigation of chaotic attractors, by de ning a suitable distortion index and to the stud...

We propose an efficient technique for the detection of errors in cryptographic circuits introduced by strong adversaries. Previously a number of linear and nonlinear error detection schemes were proposed. Linear codes provide protection only against primitive adversaries which no longer represents practice. On the other hand nonlinear codes provide protection against strong adversaries, but at ...
