CML ring oscillators: oscillation frequency
ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002In this paper an analytical model of the oscillation frequency of a differential CML ring oscillator is proposed. The model helps to choose the bias current value to optimize speed, and it is useful to estimate the oscillation frequency changes associated with the bias current change and to process tolerances.

The memristor has attracted phenomenal worldwide attention since its debut on 1 May 2008 issue of Nature in view of its many potential applications, e.g. super-dense nonvolatile computer memory and neural synapses. The Hewlett–Packard memristor is a passive nonlinear two-terminal circuit element that maintains a functional relationship between the ...

Synchronized Oscillation in Coupled Nanomechanical Oscillators
Science, 2007We report measurements of synchronization in two nanomechanical beam oscillators coupled by a mechanical element. We charted multiple regions of frequency entrainment or synchronization by their corresponding Arnold's tongue diagrams as the oscillator was driven at subharmonic and rational commensurate frequencies.

Reviving Oscillations in Coupled Nonlinear Oscillators
Physical Review Letters, 2013By introducing a processing delay in the coupling, we find that it can effectively annihilate the quenching of oscillation, amplitude death (AD), in a network of coupled oscillators by switching the stability of AD. It revives the oscillation in the AD regime to retain sustained rhythmic functioning of the networks, which is in sharp contrast to the ...

Driven oscillations of a limit-cycle oscillator
Journal of Theoretical Biology, 1980When a chemical oscillator exhibiting a limit cycle is driven by harmonically modulating one of the rate constants, the oscillations may eventually synchronize with the driving frequency, or the two may beat. Near the transition from beating to phase locking, the oscillation frequency is pulled by the drive.

Chemical oscillator as a generalized Rayleigh oscillator
The Journal of Chemical Physics, 2013We derive the conditions under which a set of arbitrary two dimensional autonomous kinetic equations can be reduced to the form of a generalized Rayleigh oscillator which admits of limit cycle solution. This is based on a linear transformation of field variables which can be found by inspection of the kinetic equations.

“Oscillating” Metallocene Catalysts: What Stops the Oscillation?
Journal of the American Chemical Society, 2003The 150 MHz (13)C NMR microstructural analysis of polypropylene samples produced with two representative "oscillating" metallocene catalysts of largely different steric hindrance, namely [(2-(3,5-di-tert-butyl-4-methoxyphenyl)indenyl)(2)ZrP](+) and [(2-phenylindenyl)(2)ZrP](+) (P = polymeryl), and the implications on the origin of the stereocontrol are

18. Operating Point on the Characteristic Curve By operating point on the characteristic curve is meant the point on the E c — I b curve of the audion about which the grid potential and space current vary. E c is the potential of the grid with respect to the filament. If a continuous negative potential such as Q Fig.

“Oscillating” Metallocene Catalysts: How Do They Oscillate?
Angewandte Chemie International Edition, 2002Based on the results of a series of propylene polymns. using oscillating metallocene catalysts of type [(2-Ar-indenyl)2ZrCl2] (Ar = C6H5 or 3,5-(t-Bu)2-4-MeO-C6H2) with various cocatalysts (MAO, TIBAl), the oscillating behavior of the zirconocenes is discussed with respect to the rac/meso stereochem. outcome of the obtained polypropylenes.
