The p-i-n carbon nanotube (CNT) devices suffer from low ON/OFF current ratio and small saturation current. In this paper by band bending engineering, we improved the device performance of p-i-n CNT field effect transistors (CNTFET). A triple gate all around structure is proposed to manage the carrier transport along the channel. We called this structure multi-segment gate (MSG) CNTFET. Band to ...

In nano-scale CMOS technology, circuit reliability is a growing concern for complicated digital circuits due to manufacturing process variation and aging effects. this paper, statistical optimization framework presented analyze improve the lifetime of in presence degradation. The proposed takes advantage variation- aging-aware gate-level delay degradation model characterize evaluate combination...

the usage of turbochargers in diesel engines has led to the downsizing of the motors as well as usage of the waste gates in turbochargers. any dimensional reduction in turbochargers and appurtenant leads to an enhancement on the performance of internal combustion engines and in environmental problems in terms of aerodynamic, thermodynamic and mechanical specifications for both engines and turbo...

combined pet/ct scanners now play a major role in medicine for in vivo imaging in oncology, cardiology, neurology, and psychiatry. as the performance of a scanner depends not only on the scintillating material but also on the scanner design, with regards to the advent of newer scanners, there is a need to optimize acquisition protocols as well as to compare scanner performances on an objective ...

This study introduces a reversible optical fulladder. Also optical NOT and NOR gates are implemented through Electro-Absorption-Modulator / Photo Detector (EAM/PD) pairs, were utilized for fulfilling reversible R gate. Then, reversible fulladder was designed based on the proposed reversible optical R gate. The operation of the suggested fulladder was simulated using Optispice and it was fou...

5 Concept assignment identifies units of source code that are functionally related, 6 even if this is not apparent from a syntactic point of view. Until now, the results 7 of concept assignment have only been used for static analysis, mostly of program 8 source code. This paper investigates the possibility of using concept information 9 within a framework for dynamic analysis of programs. The p...

As an important step of any design flow, technology mapping, expresses logic functions of a netlist using gates from a technology library, in the presence of various design constraints. This paper proposes a new approach to technology mapping, which relies and enhances upon several known techniques, integrated and fine tuned to work in a new way. The previous work on DAG mapping is extended, by...

We introduce a new design style called extended burst-mode. The extended burst-mode design style covers a wide spectrum of sequential circuits ranging from delay-insensitive to synchronous. We can synthesize multiple-input change asynchronous finite state machines, and many circuits that fall in the gray area (hard to classify as synchronous or asynchronous) which are difficult or impossible to...
