Biparameter Homotopy-based Direct Current Simulation of Multistable Circuits

Static Simulation of CNTFET-based Digital Circuits

   In this paper we implement a simple DC model for CNTFETs already proposed by us in order to carry out static analysis of basic digital circuits. To verify the validity of the obtained results, they are compared with those of Wong model, resulting in good agreement, but obtaining a lighter ensuring compile and shorter execution time, which are the main character...

Dynamic Simulation of CNTFET-Based Digital Circuits

   In this paper we propose a simulation study to carry out dynamic analysis of CNTFET-based digital circuit, introducing in the semi-empirical compact model for CNTFETs, already proposed by us, both the quantum capacitance effects and the sub-threshold currents. To verify the validity of the obtained results, a comparison with Wong model was carried out. Our mode...

Rational Biparameter Homotopy Perturbation Method and Laplace-Padé Coupled Version

The fact that most of the physical phenomena are modelled by nonlinear differential equations underlines the importance of having reliable methods for solving them. This work presents the rational biparameter homotopy perturbation method RBHPM as a novel tool with the potential to find approximate solutions for nonlinear differential equations. The method generates the solutions in the form of ...

Direct Statistical Simulation of Timing Properties in Sequential Circuits

Accurate timing analysis of digital integrated circuits is becoming harder to achieve with current and future CMOS technologies. The shrinking feature sizes lead to increasingly important local process variations (PV), making existing methods like corner-based static timing analysis (STA) yield overly pessimistic results. In this paper we propose a general purpose statistical circuit simulator ...
