Abstract
A dual mode focal plane array having a readout integrated circuit (IC) is provided herein that is electrically switchable between a first mode (e.g., direction injection mode) and a second mode (e.g., buffered direction injection) based in part on a level of a detection current. The IC includes a switching network disposed between an operational amplifier and a switching element to transition the IC between the first and second mode responsive to a control signal. The control signal can include instructions to open or close the one or more switches of the switching network and thus transition the IC between the different modes.
