摘要

本文介绍了一种10位1gs /s电流导向CMOS数模转换器。测得的INL优于+/-0.2 LSB。通过完全定制设计的温度计解码器获得了1 GS/s的转换率。解决了动态限制，在高达1 GS/s的所有转换速率下，从DC到Nyquist的间隔内测量到的SFDR超过61 dB。在这个转换率下，功率消耗等于110兆瓦。该芯片采用标准的0.35 /spl mu/m CMOS技术进行处理，有效面积仅为0.35 mm/sup / 2/。

A 10-bit 1-GSample/s Nyquist current-steering CMOS D/A converter

In this paper, a 10 bit 1 GS/s current-steering CMOS D/A converter is presented. The measured INL is better than +/-0.2 LSB. The 1 GS/s conversion rate has been obtained by a fully custom designed thermometer decoder. The dynamic limitations have been solved, resulting in more than 61 dB measured SFDR in the interval from DC to Nyquist at all conversion rates up to 1 GS/s. At this conversion rate, the power consumption equals 110 mW. The chip has been processed in a standard 0.35 /spl mu/m CMOS technology and has an active area of only 0.35 mm/sup 2/.
