Abstract

In a digital camcorder system, an A/D converter which converts the analog CCD (charge coupled device) signal into digital codes has an important role in determining the system performance. An A/D converter which has an 8-bit resolution and a 40 MSPS conversion speed is proposed. It has a ping-pong architecture. With 0.8 μm double poly and double metal CMOS technology, the experimental prototype of the proposed A/D converter has a ±0.5 LSB integral nonlinearity error (INL) and ±0.5 LSB differential nonlinearity error (DNL)
