Abstract :
This paper presents a computationally efficient physics-based compact model designed for conventional CNTFETs with MOSFET-like operation. A key novelty is the implementation of a new analytical model for channel charge. The model is cross-linked with Boltzmann Monte Carlo (MC) simulation. Comparison of electrical characteristics from MC simulation and compact modeling demonstrates the model's accuracy within its validity range. Furthermore, the compact model is used to determine CNTFET threshold voltage distribution and evaluate propagation delay dispersion in a ring oscillator, based on a study of CNT diameter dispersion across three technological processes.
