Paper Abstract

The circuit presented in this paper associates the classical direct injection and integration for each pixel with a random access scanning for the array. This focal plane implementation has two major advantages : i - the design of the pixel allows a larger integration capacitance in the 70 m pitch. ii - in the large arrays, the random access addressing mode allows the selection of sub-pictures for signal processing. The device is described. Performances of 32*32 pixels 70 m pitch circuits hybridized to CMT diodes arrays (cut-off wavelength : 5.5 and 10.1 m) are presented.
