<p>A low-noise active pixel circuit is disclosed (Fig. 9) that efficiently suppresses reset (kTC) noise by using a compact preamplifier consisting of a photodetector and only three transistors of identical polarity, in conjunction with ancillary circuits located on an imager's periphery. The use of only three transistors with a tapered reset signal allows the optical area to be increased, while still providing a low-noise imager.</p> |
