Evolution of Oscillation in a Quadrature Oscillator
2011 24th Internatioal Conference on VLSI Design, 2011The growth of oscillation in a quadrature oscillator that employs phase shifters in the coupling-path between a pair of LC-loaded negative resistance cores, is analyzed. Such an oscillator is known to have two stable modes of oscillation. Under a noise-initiated startup from an unstable initial condition, quasiharmonic assumption and the Method of ...

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.

International Journal of Bifurcation and Chaos, 2008
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.
