Abstract
Techniques are disclosed that provide time delay integration (TDI) in detection signal processing (such as a signal generated by an IR sensor). The techniques can be implemented, for example, to provide blanking and/or TDI functionality at the readout integrated circuit (ROIC) level for active focal plane array (FPA) elements or other transducer elements. In one example embodiment, an integrator circuit is configured with one or more switches for allowing integration of multiple input signal events such that reset of the integration is controlled independently and can be reset equal to or less often than the number of single events, thereby allowing one or more detected events to be integrated together within a frame interval.
