The task of identifying the non-linearity of ferroelectric devices by using a ‘Quartic Double Well’ (QDW) model is addressed. A strategy for the estimation of model parameters fitting the dynamic behaviour of the device in a large range of frequencies is discussed. An experimental set-up for investigating the dynamic behaviour of a ferroelectric device is described and results are presented showing the capability of the proposed model to reproduce the hysteresis loops, at various frequencies and forcing field amplitudes.
