Small signal amplification caused by nonlinear dielectric properties of TGS: Theoretical prediction and experimental verification below period doubling and symmetry breaking bifurcations

摘要: Abstract A series resonance circuit with ferroelectric TGS-capacitor is a practical realization of nonlinear dynamical system. Depending on external parameters (e.g., amplitude and frequency the driving voltage or temperature material) it possible to observe period doubling symmetry breaking bifurcations chaotic behavior. It can be shown theoretically that near such instabilities system act amplify small signals suitably chosen frequencies. This effect has been investigated experimentally in bifurcations. The experimental results are good agreement theoretical predictions.
