Summary:Empirical modeling of the polarization-electric field (P-E) relationship of ferroelectric capacitors subjected to the application of arbitrary electric fields is investigated. Experimental data generated by other researchers has shown that ferroelectric switched charge remains approximately constant when the capacitor is subjected to electric fields which alternate between two fixed values. The current model is based on a dual curve-fit approach to achieve the desired response. The model predicts both saturated- and minor-loop hysteresis when compared to experimental data.
