On-line quiescent state monitoring is achieved by utilizing the dual comparators compatible with IEEE std. 1149.4 analog DFT. Statistical analysis is used to minimize the impacts of dynamic signal and noise carried in the signal line. The experimental results confirm the mathematical analysis and assure test methodology.
