For the recent CMOS feature sizes power dissipation becomes an overriding concerns for VLSI circuit design. We propose a novel approach named tri-state elastic buffer design which reduces the total power, area & delay of elastic buffer. The paper presents a design and implementation of tristate buffer mechanism in 120 nm technology. This design offers also the advantage of third state (High Imp...

First-principles studies of the formation and dynamics of silicon interstitial-clusters suggest a possible growth mechanism of silicon interstitial-chains as seen in macroscopic {311} planar defects. The relative populations of the three lowest-energy silicon tri-interstitials equilibrate within a few microseconds. Unfortunately, the tri-interstitial chain is unstable, quickly decaying to the g...


 Tri-State Logic device effectively connects many devices into the same data line for transfer. The Tri- State TTL inverter has three output states such as LOW, HIGH, and open or high-impedance (High-Z) states. High-Z state either electrically isolates from transmission them one at a time to line. measurement of floating (opened disconnected) is challenging task. This issue can be resolve...

Testing Tri-state and Pass Transistor Circuit Structures. (August 2005) Shaishav Parikh, B.E., L.D. College of Engineering Co-Chairs of Advisory Committee: Dr. Duncan M. (Hank) Walker Dr. Jiang Hu Tri-state structures are used to implement multiplexers and buses because these structures are faster than AND/OR logic structures. But testing of tri-state structures has some issues associated with ...
