Otft Modelling And Characteristics

Considering that a standard OTFT model is not established; yet, in this chapter we give a brief explanation about the models used in our design. The operation of OTFTs in general is explained qualitatively and, for each technology, the models used to describe the OTFT performance are presented. The OTFT characterisation masks designed for model parameter extraction are also described. We also summarise the typical model parameter values and the typical characteristics of OTFTs and give some characterisation of OTFT variability.
