Organic electronics are suitable to wearable bio-sensing devices which can sense health conditions by printed sensors and perform signal processing and wireless communication by printed integrated circuits. Operational amplifiers (OPA) are one of the most useful circuits for analog signal processing in such devices because of the high versatility. However, few studies on organic OPAs have been reported so far, and all printed organic OPAs have required supply voltages higher than 40 V. In this paper, we show organic OPAs with printed electrodes and semiconductors operatable at 5 V. Their versatility for a variety of signal processing will be demonstrated, including amplification, integration, differentiation, current-voltage conversion, and oscillators.
