- 論文の詳細を見る
We have proposed a novel parallel-element simulation program with integrated circuit emphasis (SPICE) model for ferroelectric capacitors, in which Schmitt trigger circuits are used for representing dipoles in the ferroelectric films. It is found that the model expresses the hysteretic characteristics of polarization accurately, even when voltages are applied asymmetrically to the capacitors. We have also proposed a method to introduce the polarization reversal time in the proposed model and demonstrated the circuit response for high-speed pulses in which the polarization reversal time cannot be neglected.
