【摘要】：由于具有天然的非易失性和极低的动态功耗,应变调制型多铁异质结在后摩尔时代新型电子技术中具有广阔的应用前景。通过分析反映磁致伸缩层磁化强度动态特性的Landau-LifshitzGilbert(LLG)方程,并参考电容的伏安特性,建立了该器件的一种HSpice电路仿真模型。仿真结果表明,在应力时钟的驱动下,磁化强度完成了面内180°翻转,实现了两个逻辑稳态之间的转换。随后,通过将HSpice仿真结果与物理模型的数值分析结果进行对比,验证了电路模型的有效性。研究结果为今后基于应变调制型多铁异质结器件设计大规模集成电路奠定了基础。
[Abstract]:Because of the nature of non-volatile and very low dynamic power consumption. Strain-modulated polyferric heterostructures have broad application prospects in the new electronic technology in the post-Moore era. Landau-LifshitzGi, which reflects the dynamic characteristics of magnetization in magnetostrictive layers, is analyzed in this paper. Lbert (. LLG) equation. According to the volt-ampere characteristics of the capacitor, a HSpice circuit simulation model of the device is established. The simulation results show that the magnetization of the device is 180 掳flip in plane driven by the stress clock. Then, the HSpice simulation results are compared with the numerical analysis results of the physical model. The validity of the circuit model is verified, and the research results lay a foundation for the design of large scale integrated circuits based on strain modulated multi-iron heterojunction devices in the future.
