摘要

提出了一种基于分段多项式的关联变换算法(PWPAT)，用于系统级电路设计中非线性电路的宏建模。生成的约简模型既能提供全局精度，又能提供局部精度，且维数最紧凑。数值算例将其与现有算法进行比较，验证了其在高次谐波仿真中的精度优于传统的轨迹分段线性(TPWL)方法。

Piecewise-polynomial associated transform macromodeling algorithm for fast nonlinear circuit simulation

We present a piecewise-polynomial based associated transform algorithm (PWPAT) for macromodeling nonlinear circuits in system-level circuit design. The generated reduced model can provide both global and local accuracies with the most compact dimension. Numerical examples compare it with existing algorithms and verify its superior accuracy in higher order harmonics simulation over traditional Trajectory Piecewise-Linear (TPWL) approach.
