Recently,Professor Zhang Min, Zhu Tianyu and Wang Wanting, the corresponding author and the first authors of our research group, published the research results entitled “An Intrinsically Flexible All-carbon Differential Amplifier with High Gain and Bandwidth” on 2023 IEEE International Flexible Electronics Technology Conference (IFETC).

In this work, we demonstrate an intrinsically flexible differential amplifier with a zero-V gs connected transistor load based on p-type carbon nanotube thin-film transistors. The amplifier exhibits a direct current gain (DC-gain) of 34.1 dB and a unity gain bandwidth of 102 kHz. Importantly, the amplifier shows robustness with no significant degradation in performance when bending at radius of 5 mm. This flexible amplifier is highly promising for applications in soft electronics and Internet of Things analog front ends.
