On Bridging Faults in ECL Circuits
S.M. MenIon, Anura P. Jayasumana, Yashwant K. Malaiya · 2005
With the recent achievement of lower power and higher densi- ties, ECL technology is txpected to be used widely in high per- formance digital circuits. Recent investigations have revealed that bridging faults can be a major failure mode in ICs. This paper presents a detailed analysis of bridging faults in ECL. Eflects of bridging faults between logical units without feedback and logical units with feedback in ECL are presented. An An- alytical approach is presented for computation of logic levels at ECL outputs under varying unknown bridging resistances.
