英文摘要	This paper presents a novel two-step pixel-level analog-to-digital converter (ADC) design, which is embedded in a 17??m-pitch pixel for Infrared Focal Plane Array (IRFPA). Digitization includes two successive steps: the first is reciprocal and the second linear. With the reciprocal conversion, a high dynamic range is achieved, and the linear conversion, on the other hand, guarantees a suitable frame rate. For verification, a 15-bit two-step ADC along with the correspondent readout modules has been designed in the 0.18??m CMOS technology. The readout circuit operates at the rate of 100fps with an ultra-low power consumption of 45.77nW per pixel. ? 2015 IEEE.; EI; 670-671; 2015-July
