Abstract

In this paper, an amplifier circuit using oxide TFTs for amplifying brain signal is proposed. The proposed circuit is largely composed of two TFTs. It consists of a driving transistor that receives an input and a load transistor that determines the voltage gain through interaction with the driving transistor. Based on depletion load inverting amplifier, we analyzed the small signal modeled circuit. By using a circular TFT called Corbino-TFT, we were able to obtain a greater voltage gain. The measurement results were compared with the calculated voltage gain. In addition, to get a higher gain, method of connecting two amplifiers in series is presented and simulation results are also presented.
