Abstract
An infrared detector assembly is disclosed which includes a photosensitive layer (111) and a first planar contact structure (113) conductively coupled to the photosensitive layer for collecting charge carriers generated by radiation incident on the photosensitive layer. The detector assembly further includes a second planar contact structure (119) substantially coextensive with and separated from the first planar contact structure. A dielectric layer (115) separates the first and second planar contact structures. The first and second planar contact structures and the dielectric structure form a feedback capacitor which is integral with the detector assembly and which provides feedback capacitance for an externally provided amplifier.
