Chauchin Su, Chih-Hu Wang, Wei-Juo Wang, IS Tseng · 2003
On-line quiescent state monitoring is achieved by utilizing dual comparators compatible with the IEEE 1149.4 standard analog DFT. Statistical analysis is used to minimize the impacts of dynamic signals and noise carried in the signal line. The experimental results confirm the mathematical analysis and assure the test methodology.
