Abstract

There is an established need for a readily available, low cost, low noise, high performance ROIC and FPA to support rapid turnaround low-cost New Space earth observing missions. However, there is a dearth of space qualified commercially available sensors. The design presented is developed to address a variety of push broom TDI scanner format used in earth observing payload. Both panchromatic and multispectral sensors are developed. The sensor is highly configurable for the mission with programmable gain, on-chip programmable bit depth ADC, on-chip programmable biases, programmable digital TDI stages, and serial digital output interface. The ROIC offers embedded silicon detectors, that can be optimized for producing monolithic FPAs for UV, for visible band and for NIR band. The design is also compatible with a variety of IR detectors from SWIR through MWIR bands. This ROIC will enable a cheaper FPA alternative for rapid space missions.
