This letter demonstrates amplifier design with amorphous-hydrogenated-silicon thin-film transistors (TFTs) for high dc gain. High dc gain is achieved by using positive feedback to improve load impedance. The transfer characteristics of the amplifier are resistant to threshold voltage shift in the TFTs.
