We propose a novel amplifier design for organic thin-film transistor (OTFT), which is robust against temporal characteristics degradation.
The proposed circuit consists of two pairs of OTFT-based resistor and p-type OTFT, each for bias generation and amplification stages. By using the same configurations for the two stages, the proposed circuit compensates the characteristic degradation of the OTFTs, maintaining the proper bias voltage condition for a long period of time.
Experimental results show that the proposed amplifier achieved a 20 dB gain and a cutoff frequency of 40 Hz at a drive voltage of 2.5 V.
In addition, the proposed circuit operates successfully without significant bias drift nor gain degradation after a total of 90 minutes of continuous operation and after one month of environmental degradation.
