Abstract:The increasing interest towards organi c circuits raises the need of the spice-like mode for organic thin film transis tors (OTFTs),which can be used for electronic design automation (EDA) to provide the simulation and analysis of OTFT-based circuits.In this paper,a compact spi ce-like model for OTFT suitable to be executed on usual simulation platforms,wh ich describes the direct current (DC) electrical characteristics of OTFTs based on the equivalent circuit is derived to capture the ocmmon points but not the de tails which might be different in different OTFTs and explain several features t h at have been reported for current-voltage curves.There are several parameters i n this model,which can easily by extracted from experimental characteristic curve s.Furthermore,a type of top source and drain contact (TC) pentacene TFT is resea rched and its parameters are extracted from experimental data.With these paramet ers and the model,simulation results are obtained,which show a very good agreeme nt with measured curves in both transfer and output characteristics,so the accur acy of the spice-like model and the extracted parameters are verified.The compa ct spice-like model should be accurate enough in describing DC characteristics of OTFs,and also presents a high level of accuracy in organic integrated circuit simulation based on OTFTs.
