- 論文の詳細を見る
A circuit simulation model of ferroelectric capacitors was developed. Because of the complicated voltage and time dependence of polarization switching, simulation of the hysteretic behavior was applicable in the limited condition where the voltage change was of a constant rate or step like. The new model consists of parallel element capacitors each of which has different coercive voltage, switching charge and switching response to the voltage change. The model can be implemented in a SPICE simulator with simple expression, and it successfully reproduces the voltage and time dependence of polarization change under arbitrary conditions. Circuit simulation using this model can easily predict the behavior of ferroelectric capacitors and problems in the device operation. [DOI: 10.1143/JJAP.41.2654]
