This proposal outlines a digital pixel readout integrated circuit (DPROIC) to achieve extremely high dynamic range, high speed and elegant functionality for infrared image focal plane arrays. This digital pixel readout will be a complete camera-on-chip architecture when combined with single or dual polarity dual band detectors in a hybrid fashion. It will have a wide operating temperature range to support a broad range of detector architectures. The proposed DPROIC will be implemented in a mature CMOS process with much more reasonable mask costs as compared to that of state-of-the-art line width processes, saving money and broadening the possible supplier base. The final product will be flexible enough to be used as a generic readout integrated circuit for a broad range of NASA missions and other applications.
