This paper describes a dictionary method based on slope fault feature for hard and soft faults diagnosis of modular analog circuit. In complicated circuit when the closed-loop operational amplifier (CLOA) is used as a basic building block, the circuit can be divided into several modules based on the CLOA, and then extract the unified slope fault feature of each module to establish fault dictionary, which can diagnose hard and soft faults of all the components and the OA of the corresponding module. Finally, experiments are demonstrated to validate the efficiency of the proposed approach: the coverage of hard and soft faults of OA is 64.4% and 86.4% respectively, and the fault coverage of passive components is 100%.
Keywords:analog circuit; fault diagnosis; CLOA; slope fault feature; modular
