Generation of equivalent circuits from physics-based device simulation

Generation of equivalent circuits from physics-based devicesimulation

A novel technique for the numerical extraction of equivalent circuits from physics-based device simulation is presented. The method is based on the partitioning of the device into functional regions, each corresponding to a circuit block. All the circuit elements have a clear physical interpretation. Element values are directly obtained from small-signal dc device simulation. The method generat...

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...

Development of RF equivalent circuit models from physics-based device models

Modern device modeling codes enable the designer to simulate the behavior of nearly arbitrary 3-dimensional semiconductor device structures with multiple electrodes. However, the output of such programs is not a lumped element model that can be used in the design of RF circuits. Rather, such programs produce a (hopefully) good simulation of an experimental situation, as described by the device ...
