Neighbor Current Ratio (NCR): A New Metric for IDDQ Data Analysis
IDDQ test loses its effectiveness for deep sub-micron chips since it cannot distinguish between faulty and fault-free currents. The concept of current ratios, in which the ratio o...

Time-and-Frequency-Hopping Optical Orthogonal Codes with Hierarchical Cross-Correlation Constraints for Service Differentiation
— In this paper, we consider time-and-frequency hopping (TFH) codes for optical code-division multiple-access (OCDMA) networks. To support the differentiated service requirements...
