A model for thin film PZT ferroelectric capacitors is presented. An expression for the switching current as a function of instantaneous values of polarization and voltage, that is not explicitly a function of time is proposed. We call this a time independent model. Hysteresis, non-switching and switching current responses of these capacitors have been simulated, showing a good agreement with the experimental data.
