VHDL-AMS Simulation Framework for Molecular-FET Device-to-Circuit Modeling and Design

Figure 1

Flow of methodology. (a) The OPV molecule coupled to the electrodes through oxygen linkers is simulated in ATK for - characteristics. The conduction through the molecule is calculated at different bias conditions by the three models: semiempirical look-up table SE-LUT, transmission spectrum based (TSB) model, and FET-based equivalent model FBE. (b) VHDL-AMS based engine elaborates the results obtained by the three models, generates the corresponding - characteristics, and provides the description of MOL-FET in VHDL-AMS. (c) Logic circuits based on MOL-FET can be hierarchically implemented. Correct circuit behavior and performance can be evaluated by the simulation of the circuits.
