ABSTRACT:
The invention relates to charge injection devices (CID) for sensing IR image intensity information obtained from a two dimensional array of dual-gate sensing sites on an InSb or HgCdTe substrate, and more particularly to a novel push-pull readout circuit which eliminates the pedestal due to capacitive coupling between gates on the same pixel of a dual gate CID. The CID is scanned in rows and read out in parallel columns. Pedestal cancellation is achieved in one example by resetting the prior row as a selected row is injected. In a second example pedestal cancellation is achieved by adding an additional row which is reset as each row is injected, while in a third example a pedestal cancellation network is provided associated with each column output circuit.
