摘要
从描述铁电电容的P V滞回特性出发 ,本文在ZSTT宏模型的基础上提出了一个改进的铁电电容宏模型 ,并成功利用此模型对铁电存储器 (FeRAM)进行了电路优化和电路模拟 .最后将试图对此模型做进一步的推广 。
An improved macro model is proposed based on ZSTT model,which is derived from th e hysteresis loop of a ferroelectric capacitor.This model is proved to be very s uccessful in the optimization and simulation for FeRAM design.It can also be ada pted to express the P-V characteristic of a ferroelectric capacitor imposed by nonsymmetrical voltage,which is useful in some new operation scheme.
