Organic transistor based printed circuit unit

Abstract

A printed circuit unit based on an organic transistor comprises a signal input circuit, a load circuit and a level shifting circuit; wherein, the signal input circuit comprises N organic transistors which are serially connected in series. When one of the organic transistors connected in series is closed, the output current of the whole signal input circuit is led to be under a cut-off state, thusensuring the circuit to be able to output a correct voltage level. The level shifting circuit also comprises an organic transistor with a grid receiving inputting signal. The organic transistor can not only be used as a load but also can improve the gain of the level shifting circuit.

Description

technical field [0001] The present invention relates to a printed circuit, in particular to a printed circuit unit based on organic transistors. Background technique [0002] With the advancement of science and technology, many information devices are constantly being introduced, which brings a lot of convenience to human beings, such as radio frequency identification (RFID) tags. Radio frequency identification tags can be used in shopping centers, logistics, transportation and other places. However, in terms of product technology, traditional inorganic material chips have high process complexity and high cost, so that in the need for parity and a large number of applications, it is necessary Difficult to strike a balance between convenience and cost. [0003] Therefore, in recent years, the related process technology of organic materials has been continuously developed. It is hoped that the logic circuit can be directly printed on the film by printing with the relative sim...
