Pristine Li-Al LDHs are synthesized by hydrothermal process in different reaction conditions by varying the aging time for 1 and 24 hours. Both the Li-Al layered double hydroxides (abbreviated as Li-Al LDH1 and Li-Al LDH24 for aging time 1 hour and 24 hours, respectively) were modified by using sulphanilic acid sodium salt hydrate, modified agent to form modified Li-Al LDH1-SAS and Li-Al LDH24-SAS. The morphology of the pristine layered double hydroxides are investigated by using wide angle X-rays diffraction, scanning electron microscopy and particle size analyzer which indicates that the crystallinity and aspect ratio is increased with increasing the aging time from 1 hour to 24 hours. The particle size of Li-Al LDH24 and Li-Al LDH1 are found to be ~1000 nm and ~250 nm, respectively. Both the pristine and modified LDHs are characterized by XRD, FTIR spectra and thermogravimetric analysis.

本研究目的在於改变长晶时间的长短，合成出同径大小的Li-Al LDHs，再经由改质剂sulphanilic acid sodium salt hydrate将Li-Al LDHs无机层材表面有机官能化制备出改质型Li-Al LDHs-SAS，於是进一步藉由扫描式电子显微镜、射径仪和穿透式电子显微镜等仪器分别观察LDHs改质前和改质后其主层结构型态上的变化；从中可以发现Li-Al LDHs随著长晶时间的增加其径有随之增大的趋势，但经有机化改质后其径会由於改质环境的影响明显低许多，针对此现象本实验将未改质和改质后之Li-Al人工无机层材制备成复材进一步探讨其在热性质和难燃特性上的为表现。

This compensation circuit can make the stability of the LDO linear regulator undependent on the effect of load capacitor's equivalent serial resistance, and it also makes the unit gain frequency bandwidth change slightly when the load is varying, thus greatly improving the performance of transient response, Furthermore, on the basis of dynamic frequency compensation, an overcurrent protection circuit is designed.

文章针对LDO稳定性的问题，提出了一种内部动态频率补偿电路，使LDO线性稳压器的稳定性不受负载电容的等效串联电阻的影响，其单位增益带宽也不随负载电流变化而改变，大大提高了瞬态响应特性；采用Hynix 0.5μm CMOS工艺模型对电路进行仿真；此外，该电路在实现动态频率补偿的基础上又加入了系统的过流保护功能，当负载电流大于限制电流时，LDO不能正常工作；当负载电流小于限制电流时，又自动恢复到正常工作状态。
