Organic thin-film transistor amplifiers

Abstract

This chapter provides a detailed overview of amplifier topologies that can be manufactured using organic thin-film transistors (OTFTs). Advantages and drawbacks of unipolar and complementary OTFT technologies are discussed. In the rest of the chapter, unipolar and complementary amplifier solutions are presented in sequence. First elementary unipolar amplifiers are analyzed in detail, providing quantitative insight in their performance (including gain, linearity, output swing, speed, and noise) based on a simple analytical model of the OTFT. Then examples of multistage unipolar amplifiers providing higher gain are described. Amplifiers based on complementary transistors are analyzed later, focusing on their benchmarking against unipolar solutions. Several complementary organic amplifiers exploiting multistage topologies are finally discussed, providing an analysis of their performance and their experimental characterization.
