一种基于灵敏度分析的模拟电路子网络级诊断算法

A Diagnosis Algorithm of Subnetworks in Analog Circuits Based on the Sensitivity Analysis

本文在“计算节点电流和”灵敏度分析和KCL基础上，提出了一种新的子网络组的诊断算法。运用本文算法，能够准确地确定出故障子网络（或故障元件集合）和非故障子网络（或非故障元件集合），因而将故障定位在更小的范围。本文算法计算量小、可靠，适合于大规模电路。

This paper presents a diagnosis algorithm of subnetworks in analog circuits,based on the' sensitivity of compute - node - current -sumn and KCL. Faulty subnetworks (or faulty element sets) and nonfaulty subnetworks (or nonfaulty element sets) can be accu-rately determined with this algorithm. The algorithm is reliable and less computation is re-quired. It is also applicable to large networks.
