Abstract: An image detector includes an array of detector unit cells including a plurality of unit cells and a plurality of single slope analog to digital converters (SSADCs). Each of the plurality of SSADCs is coupled to an output of a different one of the unit cells. Each each of the plurality of SSADCs includes: a comparator having a positive input and a negative input and a comparator output, the comparator being contained in a first layer; and a counter coupled to the comparator output and contained in a second layer. The counter is electrically coupled to the comparator with a through a silicon via.
