This paper presents a comprehensive investigation of how transistor level optimizations can be used to increase design quality of CMOS logic gate networks. Different properties of transistor networks are used to explain features and limitations of previous methods. We describe which figures of merit, including the logical effort, affect the design quality of a cell transistor network. Further, ...

Deep-submicron CMOS designs maintain high transistor switching speeds by scaling down the supply voltage and proportionately reducing the transistor threshold voltage. Lowering the threshold voltage increases leakage energy dissipation due to subthreshold leakage current even when the transistor is not switching. Estimates suggest a five-fold increase in leakage energy in every future generatio...

In this paper, we have proposed the concept of 7Transistor SRAM. 7-Transistor SRAM has been designed to provide an interface with CPU and to replace DRAM in systems that require very low power consumption. The feature of 7Transistor SRAM like low power consumption and leakage current have been analyzed with 45nm technology. The comparative study and mathematical modeling have been proposed for ...

This work studies the effects of dynamic threshold design techniques on the speed and power of digital circuits. A new dynamic threshold transistor structure has been proposed to improve performances of digital circuits. The proposed switched-capacitor dynamic threshold PMOS (SC-DTPMOS) scheme employs a capacitor along with an NMOS switch in order to effectively reduce the threshold voltage of ...

The hairpin ribozyme is a naturally occurring catalytic RNA composed of two helix-loop-helix domains, A and B, that dock to form the biologically active enzyme. Previously, the crystal structure of the hairpin has been solved as a four-way helical junction that incorporated the U1A protein as an artificial crystal-packing motif [Rupert & Ferré-D'Amaré (2001), Nature (London), 410, 780-786].
