Fig. 2 Signal-to-noise ratio (SNR) of the APS measured at different The general structure of our APS pixel with an internal measured reset signal and output of the pixel. sensing lower light levels requires higher integration times The measured output of the APS with integrator is Figure 6 shows how the output of the APS with integrator The output noise level of the APS with transistor APS pixel. Fig. 6 Output of the APS with integrator, sampled at different levels The APS with integrator structure has a low fill-factor. The APS with a comparator pixel is CMOS photodetector systems for low-level light applications CMOS photodetector systems for low-level light applications ./cache/work_gynfkaaenfhqhn667qlzxlkemq.pdf ./txt/work_gynfkaaenfhqhn667qlzxlkemq.txt
