CMOS Active Pixel Sensor with On-Chip Successive Approximation Analog-To-Digital Converter
نویسندگان
چکیده
The first CMOS active pixel sensor (APS) with onchip column-parallel successive-approximation analog-to-digital converter (ADC) is reported. A 64 64 element CMOS APS implemented in a 1.2m n-well single-poly, double-metal process with 24m pixel pitch is integrated with a 64 1 array of column parallel successive approximation 8-b ADC’s. Good image quality was observed. The capacitively-coupled ADC’s dissipate approximately 1 W-s/ksample and occupy 0.05 mm of chip area.

متن کاملA Nyquist-Rate Pixel-Level ADC for CMOS Image Sensors - Solid-State Circuits, IEEE Journal of
A multichannel bit-serial (MCBS) analog-to-digital converter (ADC) is presented. The ADC is ideally suited to pixel-level implementation in a CMOS image sensor. The ADC uses successive comparisons to output one bit at a time simultaneously from all pixels. It is implemented using a 1-bit comparator/latch pair per pixel or per group of neighboring pixels, and a digital-to-analog-converter/contro...

This paper presents a fast multiple sampling method for low-noise CMOS image sensor (CIS) applications with column-parallel successive approximation register analog-to-digital converters (SAR ADCs). The 12-bit SAR ADC using the proposed multiple sampling method decreases the A/D conversion time by repeatedly converting a pixel output to 4-bit after the first 12-bit A/D conversion, reducing nois...
