Abstract :
The authors examine the suitability and use of polysilicon thin-film transistors (TFTs) for analog circuit applications. It is shown that the electrical characteristics of TFTs present significant problems for analog design and are likely to make new design techniques necessary. Nevertheless, an operational amplifier built with TFTs is demonstrated, the performance of which is adequate for many basic signal processing functions. A CMOS polysilicon TFT technology was chosen for this study.<>
