Organic dendrimers are a fascinating new class of materials for opto-electronic applications. We present coupled electronic oscillator calculations on novel nanoscale conjugated dendrimers for use in organic light-emitting diodes. Strong confinement of excitations at the center of the dendrimers is observed, which accounts for the dependence of intermolecular interactions and charge transport o...

Oscillators are integral part of many electronic systems. An oscillator is an electronic device used for the purpose of generating a signal. Most electronic signal processing systems require frequency or time reference signals. This paper deals with the analysis and design of CMOS oscillators more specifically voltage controlled oscillators (VCOs).Voltage Controlled Oscillator is an electronic ...

Oscillators are kernel components of electrical and electronic circuits. Discussion of history, mechanisms and design based on Barkhausens observation. Discussion of a Wien Bridge oscillator based on the question: Why does this circuit oscillate ?

We consider the electronic structure of a shunt-fed Colpitts oscillator. This oscillator is a feedback circuit built with a single bipolar junction transistor which is responsible of the nonlinear behavior of the complete circuit. The interest of investigating the dynamics of this circuit is justified by its multiple potential applications in the field of engineering and also by the striking/tr...

A method is proposed for detecting from univariate data the presence of synchronization of a self-sustained oscillator by external driving with varying frequency. The method is based on the analysis of difference between the oscillator instantaneous phases calculated using continuous wavelet transform at time moments shifted by a certain constant value relative to each other. We apply our metho...

We construct electronic oscillator from acellular slime mould Physarum polycephalum. The slime mould oscillator is made of two electrodes connected by a protoplasmic tube of the living slime mould. A protoplasmic tube has an average resistance of 3 MOhm. The tube’s resistance is changing over time due to peristaltic contractile activity of the tube. The resistance of the protoplasmic tube oscil...

We perform an analytical study of the correspondence between a classical oscillator with frequency perturbed by a coloured noise and the one-dimensional Anderson-type model with correlated diagonal disorder. It is rigorously shown that localisation of electronic states in the quantum model corresponds to exponential divergence of nearby trajectories of the classical random oscillator. We discus...
