A basic circuit theory of fault diagnosis for analog circuits with parameter tolerance is proposed in this paper. The approach uses the direction vector of voltage increment in test nodes as a fault signature for predefined faults. A linear equation is built to locate a faulty element. On the condition that the component tolerances are taken into account, the concepts of direction vector and fuzzy analysis method are combined together to analyze a parametric fault. Examples illustrate the proposed approach and show its effectiveness.
