Paper Abstract

This paper reports the design and test of an improved direct-injection readout circuit for infrared focal plane arrays (IRFPA). In this circuit, two selectable capacitors are added in the pixel to accommodate the wide range of illumination conditions. The circuit also supports image transposition (invert/revert). A 128×128 pixels readout circuit chip which uses this improved readout circuit structure has been fabricated. A simple test bench is established to verify the availability of the readout chip. The testing method and results are also presented in this paper. The testing results show the good performance of the readout chip.
