Abstract

A new current readout structure for the infrared (IR) focal-plane-array (FPA), called the switch-current integration (SCI) structure is proposed and analyzed. It is found that the proposed SCI readout structure can achieve a good readout performance in a small pixel size. It is clearly shown through the analysis that the proposed SCI readout structure and the associated design technique can be applied to the high density and high performance readout circuit design. The high injection efficiency, good detector bias, high detectivity, and large storage capacity readout performances are achieved in a 50 X 50 micrometers ² pixel size.
