Abstract
An adaptive amplifier circuit with minimal excess noise and a linear charge-handling capacity exceeding 10 electrons to enable high-quality imaging at long wavelength infrared backgrounds and video frame rates with enhanced dynamic range is disclosed. An integration capacitor stores a charge produced from a photodetector. An adaptive skimming circuit skims off excess charge during integration of the charge on the integration capacitor. A switched-capacitor low pass filter provides enhanced dynamic range.
