摘要：Flexible/stretchable electronics is a promising field for the application of carbon nanotube (CNT) thin-film transistors (TFTs), which possess high mobility and mechanical flexibility. Analog circuits such as amplifiers and analog front-end circuits, which are used to amplify weak sensing signal and convert it to digital signal, are the essential circuits for flexible sensor applications. We have studied the circuit design technologies as well as the device fabrication technology to realize analog circuits using CNT TFTs. The most challenging issue was the device-to-device variation in characteristics. We developed the circuit design technologies to avoid the effect of the characteristic variations, realizing the flexible analog frontend circuit which can be operated stably at low voltage. [1] The advantage of CNT-based flexible electronics was clarified by showing outstanding figure-of-merit of the A/D converter.
