摘要

提出了一种生成模拟电路模块时变线性化宏模型的方法。由于这些模型具有经过认证的稳定性，因此可以用于执行非平稳操作条件下的快速小信号分析。考虑到电源完整性评估应用，我们通过对低差(LDO)稳压器进行布局后仿真来验证所提出的方法。

Fast LDO Simulations via Parameter-Varying Linearized Macromodels

An approach for generating time-varying linearized macromodels of analog circuit blocks is presented. These models can be used to perform fast small-signal analyses characterized by nonstationary operating conditions, thanks to their certified stability. We validate the proposed approach by performing post-layout simulations of a Low DropOut (LDO) voltage regulator, in view of power integrity assessment applications.
