摘要

本文介绍了一种基于63个二进制非加权电流单元的视频8位D/ a转换器的设计和测试，6个msb按8/spl × 8矩阵排列，2个lsb按2个二进制加权电流单元排列。每个电流单元都有一个平衡的输出。级联晶体管用于提高开关电流单元的精度和速度。利用HSPICE对该设计进行了仿真，并在ES2 1.5 /spl mu/m CMOS工艺下进行了处理。测量结果包括在内。

Full custom CMOS design and measurement of a video D/A converter

This paper describes the design and testing of a video 8-bit D/A converter, based on 63 binary non-weighted current cells, arranged in a 8/spl times/8 matrix for the 6 MSBs and 2 binary weighted current cells for the 2 LSBs. Each current cell is provided with a balanced output. Cascode transistors are used to increase the accuracy and speed of the switching current cells. The design has been simulated with HSPICE and processed in ES2 1.5 /spl mu/m CMOS technology. Measurement results are included.
