A low-leakage current and low-operating-voltage buried-photodiode structure of CMOS image sensors has been developed. The new structure adopted a modified fabrication process as well as an additional ...

A novel 256/spl times/256 CMOS active pixel sensor (APS) system with 12 bit, 6.3 Msample/s (MS/s) CMOS pipelined analog to digital converter (ADC) integrated on chip is presented. The test chip has ...
