ACTIVE PIXEL SENSOR AND ANALYTICAL DEVICE USING THE SAME

摘要

An active pixel sensor (124) having at least one pixel (134) is disclosed. The pixel (134) comprises at least one photodiode (144) and at least one readout circuit (152). The readout circuit (152) comprises at least one integrating capacitor (156). The readout circuit (152) is adapted to accumulate electrical charges generated by the photodiode (144)during illuminating the photodiode (144) within the integrating capacitor (156). The readout circuit (152) further comprises at least one selector switch (164) adapted to read out the electrical charges from the integrating capacitor (156).
