Abstract :
A new model for thin film SBT ferroelectric capacitors including temperature behaviour is presented. The model, which is based on the Preisach theory, requires parameters that are physically based and which can be easily extracted from measured data. Iterative procedures are not used in the model, which makes it best suited for use in circuit simulators
