High-Speed, High-Resolution Adaptive Array Processing Advanced Filter Bank Analog-to-Digital Converter

"This SBIR Phase II project develops an adaptive processing analog-to-digital converter technology that provide up to an 8-fold increase in speed of conversion with high-resolution, wide dynamic range performance. The Adaptive-Advanced Filter Bank (A-AFB)technology provides an architecture to combine state-of-the-art converters to dramatically increase the speed while maintaining high resolution . The performance of the AFB architecture is greatly enhanced by the application of highly innovative adaptiveprocessing. By eliminating stages of RF downconversion, this technology greatly accelerates the progress toward direct digitization of wideband data directly at the antenna/aperture and substantially reduces part count, power requirements, mass, andincreases reliability. In this project, V-Corp will take this technology from the breadboard/concept phase to the fully functioning product design and prototyping stage which provides performance well beyond state-of-the art for use in a functionaldemonstration vehicle. An open architecture prototype system will be implemented to provide a versatile platform to rapidly develop, test, and integrate the very latest converters with a variety of adaptive array processing AFB algorithms, which greatly simplify calibration,track and correct errors that drift over time and temperature, and improves performance; target specifications include: 12-bit ADC with 1.0 GHz sample rate (with d
