Release of RPI Amorphous Silicon and Polysilicon
TFT Models in SmartSpice and UTMOST

Introduction

Thin film transistors (TFTs) have an important application in the manufacture of active matrix LCD displays. As this technology has become more mature, a number of different models of both amorphous silicon (a-Si) and polysilicon TFTs have been proposed. Recently two new models developed by the Rensselaer Polytechnic Institute (RPI) have been implemented in the SmartSpice circuit simulator. These models are also now available in the TFT module of UTMOST III and this article will discuss the different model characteristics, and their use in both SmartSpice and UTMOST III.
