The aim of this work is to show the dependence of the time dependent current of gate-all-around transistors on their geometries and thus to find out how to optimize their intrinsic AC behavior. The Ramo-Shockley-Pellegrini (RShP) theorem and many-particle Monte Carlo technique are used, through the recently developed BITLLES simulator which is devoted to simulate classical and quantum electronic devices,...
We present a novel method for the evaluation of shot noise in quasi-1-D field-effect transistors, such as those based on carbon nanotubes and silicon nanowires. The method is derived by using a statistical approach within the second quantization formalism and allows the inclusion of both the effects of Pauli exclusion and Coulomb repulsion among charge carriers. This way, it extends the Landauer-Buttiker...
With the event of nanoscale technologies, new physical phenomena and technological limitations are increasing the process variability and its impact on circuit yield and performances. Like combinatory cells, the sequential cells also suffer of variations, impacting their timing characteristics. Regarding the timing behaviors, setup and hold time violation probabilities are increasing. This article...
The dramatic increase in leakage current, coupled with the swell in process variability in nano-scaled CMOS technologies, has become a major issue for future IC design. Moreover, due to the spread of leakage power values, leakage variability cannot be neglected anymore. In this work an accurate analytic estimation and modeling methodology has been developed for logic gates leakage under statistical...
