Abstract

Embodiments of a read-out integrated circuit (ROIC) include a plurality of unit cells. Each unit cell includes a bias subsystem, a reset switch, at least one integration capacitor, and at least one read switch. A focal plane array includes a plurality of photo detectors disposed in a grid and a ROIC. A column buffer includes a first buffer subsystem, a feedback subsystem, a first and second correlated double sampling subsystem, and a second buffer subsystem. A ROIC includes at least one integration subsystem having a transistor subsection, a poly silicon layer, and a plurality of active layer sections.
