Circuits Systems and Does Chaos Work Better Than Noise ? 4 Successive Approximation
نویسنده
چکیده
Chaos and random signals share the property of long term unpredictable irregular behavior and broad band spectrum. The aim of this paper is not to distinguish between random and chaotic dynamics, nor to show the use of chaos, but to focus attention on how chaos and noise help order to arise from disorder. This means to investigate the effect of the introduction of either deterministic chaotic or random sequences in different types of phenomena. In particular the results related to different applications, self-organization in arrays of locally coupled systems in which a chaotic dissymmetry is present, chaos driven optimization strategies, pattern formation in Drosophila embryos and some new topics on game theory are treated with the aim to investigate the subject: “does chaos work better than noise?”. Figure 1. Chaos, depicted with its typical structure in phase plane, works better than noise in a lot of examples presented in

An 8-bit 800- μħbox W 1.23-MS/s Successive Approximation ADC in SOI CMOS
We report on an 8-bit successive approximation analog-to-digital converter (SA-ADC) that was designed and fabricated in 0.5m silicon on sapphire CMOS technology. The SA-ADC is capable of 32-MHz operation, providing 1.23-MS/s conversion rates, and consumes 800 W at 3.3-V supply. The lack of substrate parasitic capacitances enables the use of small-area capacitors and reduces the noise coupling t...
متن کاملTDMA Secure Communication Scheme Based on Synchronization of Chua's Circuits
A novel Time Division Multiple Access (TDMA) secure communication scheme is proposed based on sporadic coupling chaos synchronization. Compared with conventional chaos masking method, it has higher noise-resistibility, better security and frequency efficiency, etc. Simulation results illustrate the effectiveness and efficiency of this method. Finally, we analyze factors which affect system abil...
متن کاملSelf-Timed Architecture for Masked Successive Approximation Analog-to-Digital Conversion
In this paper, a novel architecture for self-timed analog-to-digital conversion is presented, designed using the NULL Convention Logic (NCL) paradigm. This analog-to-digital converter (ADC) employs successive approximation and a one-hot encoded masking technique to digitize analog signals. The architecture scales readily to any given resolution by utilizing the one-hot encoded scheme to permit ...
متن کاملStochastic Resonance in Deterministic Chaotic Systems
We propose a mechanism which produces periodic variations of the degree of predictability in dynamical systems. It is shown that even in the absence of noise when the control parameter changes periodically in time, below and above the threshold for the onset of chaos, stochastic resonance effects appears. As a result one has an alternation of chaotic and regular, i.e. predictable, evolutions in...
متن کاملThe Assessment of Applying Chaos Theory for Daily Traffic Estimation
Road traffic volumes in intercity roads are generally estimated by probability functions, statistical techniques or meta-heuristic approaches such as artificial neural networks. As the road traffic volumes depend on input variables and mainly road geometrical design, weather conditions, day or night time, weekend or national holidays and so on, these are also estimated by pattern recognition te...
