Abstract

See full text

id='REI-00001' date='20150428' An image sensor system using offset analog to digital converters. The analog to digital converters require a plurality of clock cycles to carry out the actual conversion. These conversions are offset in time from one another, so that at each clock cycle, new data is available.id='REI-00001' id='REI-00002' date='20150428' A CMOS image sensor converts successive analog signals, representing at least a portion of an image, into successive digital signals using an analog to digital circuit block. Multiple clock cycles may be used by the circuit block to fully convert an analog signal into a corresponding digital signal. The conversion of one analog signal into a corresponding digital signal by the circuit block may be offset in time and partially overlapping with the conversion of a successive analog signal into its corresponding successive digital signal by the circuit block.id='REI-00002'
