Abstract :
The research progress on carbon nanotube (CNT) has greatly brought new opportunities for Infrared (IR) sensors both for military and civil applications. This led to research and development of reliable nano manipulation method and high resolution CNT based Infrared (IR) imaging systems. In this paper, an adjustable bias, differential input charge integrator current amplifier was designed to read the photocurrent of Multiwall CNT (MWCNT) IR detector. Meanwhile, highly resolution and ultra fast ADC was designed in readout system (ROIC), so that it works in novel imaging recovery system. Experimental results the MWCNT IR sensors have shown that the readout system can read as low as 10pA current, and in CNT based IR imaging system, this readout system also works well.
