ABSTRACT:
A self-adjusting adaptive input circuit with minimal excess noise and a linear charge-handling capacity exceeding 109electrons to enable high-quality imaging at long wavelength infrared backgrounds and video frame rates is disclosed. An integration capacitor stores a charge produced from a photodetector. A self-adjusting current source skims a current during integration on the integration capacitor. The gate voltage of a skimming transistor is set via a programming transistor in order to set the skim level.
