Parametric Resonance in Time-Dependent Networks of Hopf Oscillators

We study a collection of limit cycle oscillators with different frequencies interacting via networks. With static networks, our specific class of models produces a frequency learning mechanism leading the collection of oscillators to ultimately adopt a sin ...

Adaptive Frequency Oscillators and Applications

Auke Ijspeert, Jonas Buchli, Ludovic Righetti

In this contribution we present a generic mechanism to transform an oscillator into an adaptive frequency oscillator, which can then dynamically adapt its parameters to learn the frequency of any periodic driving signal. Adaptation is done in a dynamic way ...

Pseudoferroelectricity: A possible scenario for doped ZnO

Alexander Tagantsev

A phenomenological Landau-theory model, where a crystal on cooling from a state with polar symmetry exhibits a maximum of dielectric permittivity and polarization-field hysteresis loops, is offered. The model is equivalent to that of a true ferroelectric i ...

Integrated Hall Microsystem with Current Re-Use

Radivoje Popovic, Pavel Kejik, Predrag Drljaca

A new architecture of a Hall microsystem for low-power applications is presented. The innovation in this paper lies in the re-use of the electric current for biasing of several parts in the microsystem permitting substantial reduction of the current consum ...

Investigation of Giant-Magneto-Impedance (GMI) effect and magnetic hysteresis in microfabricated Permalloy/Coper device

Radivoje Popovic, Pavel Kejik, Ozge Zorlu

In this paper, we present the giant-magneto-impedance (GMI) effect in a microfabricated closed Permalloy core which surrounds a copper excitation rod. We measured a 90% change in the inductance value of the device for a sinusoidal excitation at 500 kHz in ...
