Patent US 5,659,315

Apparatus for time multiplexed oversampled analog to digital modulation is provided. Embodiments generally include a plurality of energy collection elements coupled to individual pixel processors preferably mounted proximate to each energy collection element. Each pixel processor shares a common block of conversion logic to form a plurality of integration loops to process the signal generated by each energy collection element. Specific embodiments are shown using CCD, CID, FET, and charge well technologies.
