Modeling of on-off Current and Cutoff Frequency in Organic Thin Film Transistors

Abstract

Organic thin-film transistors (OTFTs) are providing incitement in various integrated circuit applications because of advantages like low cost and being flexible.In this paper we present an analytical modeling of on-off current and cutoff frequency in organic thin film transistors. The proposed model accurately describes both the parameters uniquely and is based on the standard equations of transistor . The model parameters are listed out and simulation of the final model is performed in MATLAB . Furthermore, it has been concluded that the high cutoff frequency of OTFTs can be achieved with short channel length and high gate voltage ,further high on-off current ratio can be attained by lowering semiconducting layers’ thickness and increasing the mobility.
