摘要
本文介绍了一种高速单片ＣＭＯＳ１２位Ｄ／Ａ转换器的设计。着重阐述了电阻开关网络的按比例匹配设计原理、结构特点，激光动态修调网络的结构设计，以及逻辑控制和功能特点。该Ｄ／Ａ转换器的线性误差、微分误差满刻度误差均满足１２位精度。在１５Ｖ工作电压下，满度电流建立时间为０．６μｓ，功耗２０ｍＷ。
A 12-bit high-speed monolithic CNOS D/A converter has been developed.The design of the device is described in the paper.The principle of proportional match design of tbe resistor switch network,its structural characteristics and the arrangement of the network for laser trim-ming are elaborated. Logic control and the functions of the device are also presnted. The linear error,differential error and full scale error of the converter all meet the requirements for 12-bit resolution. Operating at 15V,it achieves a settling time of 0.6μs for full scale current。
