Time-of-flight chip in standard CMOS technology with in-pixel adaptive number of accumulations

This paper introduces a Time-of-Flight sensor of 50 χ 60 pixels in standard CMOS 0.18 μm technology with in-pixel adaptive number of accumulations and background suppression. Background suppression is carried out through two mechanisms, namely, the increase of signal to background ratio, and background subtraction. The pixel features a fill factor of 77… CONTINUE READING
