A 10 bit 30 MSPS CMOS A/D converter for a high performance video application system

In a video application system, an A/D converter which converts the analog signal into digital codes plays an important role in determining the system performance. In this paper, a high performance A/D converter which has 10-bit resolution and 30 MSPS conversion speed is proposed. It has an architecture of pipeline style. With 0.5 /spl mu/m double poly and double metal fully CMOS technology, the experimental prototype of the proposed A/D converter has /spl plusmn/0.7 LSB INL, and /spl plusmn/0.5 LSB DNL.
