  • CMOS active pixel sensors have become
    strong candidates for pixel detectors used in high energy
    physical experiments. Using standard CMOS fabrication
    process, full data processing circuits can be integrated on
    the same substrate with sensors and on-chip data process-
    ing is achievable. For this purpose, a column level high
    speed low power auto-zeroed comparator is developed.
    Tested at 100MHz, a resolution better than 0.5mV was
    obtained and its output residual o®set is only 0.15mVrms.
    The dimension of the comparator is 25¹m£300¹m and its
    power dissipation is about 220¹W.
