摘要：
This brief deals with soft-fault diagnosis of analog circuits with tolerance and limited test points. Node-voltage-ratio under different current excitation is deduced to establish a fault dictionary and fault eigenvalues of circuit with tolerance are manifested to be the same as that with nominal parameters. It is proved that multiple-fault eigenvalue equation of analog circuits with tolerance holds when node voltage with nominal parameters are adopted. Three numerical examples illustrate diagnosis accuracy and effectiveness of proposed approach.
