Abstract

An object of the present invention is to apply an organic thin-film transistor, which is produced using an organic semiconductor material, to an analog amplifier. The analog amplifier according to the present invention includes: a first amplifier (2) which voltage-amplifies an analog signal to be amplified; and a second amplifier (6) which power-amplifies the thus amplified signal output from the first amplifier to generate a drive signal that drives an equipment (10). The first amplifier includes an organic semiconductor amplifier element, namely an organic thin-film field-effect transistor (4), in which a semiconductor layer forming a channel is composed of an organic semiconductor. An organic semiconductor material is solvent-soluble and thus can be applied to form a film by a printing method such as an ink-jet method. Therefore, the production thereof can be carried out using a simple production facility.
