Data conversion includes two focus areas: Ultra Low Power Analog to Digital Converters (ADCs) and Imager Readouts. The ultra low power ADCs consume about 1/10 the power as COTS ADCs. The ADCs are combined with signal processing to provide an entire analog front end. Parts targeting focal plane arrays and CCD imagers are under development.
Ultra Low Power Analog to Digital Converters (ADCs): Two ultra-low power 14-bit ADCs are under development. Power consumption is ~ 1/10 of commercial parts that are presently on the market. ADCs target imager applications.
Baseline design for quad ADC. It will have a very low noise front end and a flexible design that will support a broad range of FPA im0plementations. Front end will be deigned for easy incorporation in FPA Read Out Integrated Circuits (ROICs).
Imager Readouts: The ultra low power ADCs are combined with signal processing to provide an entire analog front end. Parts targeting focal plane arrays and CCD imagers are under development.
The new Mercury topology, only one of four ADC channels is shown for simplicity. By removing or adding sections of the ADC, it will be able to support other Nu-Trek programs that need ADCs with fewer or more bits of resolution respectively.
