A/D converters with high speed and high resolution is needed to process video signal in digital camera and mobile phone. In this paper, a 10-bits 125-MS/s pipelined A/D converter is designed to be used in CMOS image sensor systems. It consists of sample-and- hold, flash subrange-ADC, multiply-DAC and digital error correction logic. This ADC is expected to used in not only CMOS image sensor system but also communication system or set-top box.
