In this paper, a new structure of low-photocurrent CMOS retinal focal-plane sensor with pseudo-BJT smoothing network and adaptive current Schmitt trigger is proposed. The proposed structure is very simple and compact. This new circuit can be easily implemented in CMOS technology with a small chip area. Besides, another innovation of this circuit is that the proposed circuit could be operated for low-induced current level @A), and the current hysteresis of proposed current Schmitt trigger could be adjusted adaptively according to the value of induced photocurrent. In this paper, the detection of static and moving objects, such as a moving white bar, are proven by projecting a pattern through HSPICE simulation. The proposed retinal focal-plane sensor includes 32 x 32 pixel array with a pixel size of 70 x 70 pm'. The fill factor is 75% and the total chip area is 3000 x 3030 pm'. I t is with fully functional 32 x 32 implementations consuming less than 8.8 pW per pixel at 3.3 V. Measurement results present the proposed retinal focal-plane sensor could he successfully used in character recognition, such as pen-scanner or etc.
