On-line testing of analog circuits by adaptive filters

This papers describes a new technique for on-line testing of analog circuits based on plant recognition by adaptive algorithms. To the authors knowledge, this is the first time such technique is used to on-line testing of analog circuits, allowing complete fault coverage. The paper presents the testing methodology and experimental results showing easy detection of soft, large-deviation and hard faults, with a low cost digital processor. Components variations as low as 10% have been detected, as the comparison parameter (output error power) varied from 300% to 20%.
