Abstract

In this paper, we report a systematic approach to extract parameters from organic thin film transistors (OTFTs) that are used for compact Spice models. The universal organic thin-film transistor (UOTFT) model and Silvaco's Smartspice platform are utilized for simulations whereas experimental data are collected from Plastic Logic's (PL) thin-film transistors that are processed on flexible plastic substrates. The parameter extraction procedure is outlined where both current–voltage and capacitance–voltage measurements are employed. This is then followed by simulations of inverters and ring oscillators to assess the results against simple logic circuits.
