Abstract—In this paper, behavior of an oscillator under injection of another signal has been investigated. Also, variation of output signal amplitude versus injected signal phase variation, the effect of varying the amplitude of injected signal and quality factor of the oscillator has been investigated. The results show that the locking time depends on phase and the best locking time happens at...

We study nonlinear transport for two coupled one-dimensional quantum wires or carbon nan-otubes described by Luttinger liquid theory. Transport properties are shown to crucially depend on the contact length Lc. For a special interaction strength, the problem can be solved analytically for arbitrary Lc. For point-like contacts and strong interactions, a qualitatively different picture compared t...

In this work we review the processes of phase noise and jitter in electronic oscillators and the relationship between the two. Frequency and time domain simulation techniques and results are presented through the study of performance enhancement for a CMOS LC oscillator. The studied enhancements significantly reduce flicker noise upconversion, while the results demonstrate good agreement betwee...

This letter presents a low power CMOS pulse generator based on spectral efficiently gated oscillator for multiband impulse radio ultra-wideband (UWB) system. The pulse generator is based on an on/off switched LC oscillator with the trapezoid switching pulse. By using trapezoid pulse for on/off switching signal of the oscillator, better output spectral characteristic can be achieved without addi...

The analysis, design, and operation of high-voltage, transformer-coupled LC vector inversion generators are presented and discussed. The transformer-coupled LC inversion generator is easy to construct and, compared with Marx-type generators and conventional LC vector inversion generators, requires only one inversion switch, independent of the number of voltage multiplication stages. The transfo...

We investigate the dynamics of large arrays of coupled phase oscillators driven by random intrinsic frequencies under a variety of coupling schemes, by computing the time-dependent cross-correlation function numerically for a two-dimensional array consisting of 128 X 128 oscillators as well as analytically for a simpler model. Our analysis shows that for overall equal interaction strength, a sp...

This paper presents a Low power consumption & Low phase Noise Voltage Controlled Ring Oscillator (VCRO) operated at 2.45 GHz. Frequency implemented in 0.18 μm complementary metal-oxide semiconductor (CMOS) technology with the unique differential delay cell. The Voltage Controlled Ring Oscillator is design in Tanner Tool Version 13 environment. Power Consumption should be reduced to improve the ...

The complex dynamics of coupled-oscillator arrays lead to the existence of a multitude of steady-state solutions. In addition to finding or selecting a desired steady-state solution, one further needs to guarantee its stability. In this section, perturbation methods are described that allow the designer to examine both the existence as well as the local stability of the various steady-state sol...

A simulation study demonstrates how coherent control, combined with adaptive polarization pulse shaping and a genetic algorithm, may be used to simplify femtosecond coherent nonlinear optical signals of excitons. Cross peaks are amplified and resolved, and diagonal peaks are suppressed in the heterodyne-detected two-pulse echo signal from the Soret band of a porphyrin dimer coupled to a Brownia...
