高速模数/数模转换电路的研究与实现

Study and Realization of High-speed AD/DA Conversion Circuit

收发信道一直以来都是通信系统的一个重要组成部分。随着数字化集成电路的发展,高速数字电路逐步代替大部分模拟电路,而收发信道后高速的数模/模数转换电路显得尤为重要。详细介绍了一种通用的高速模数/数模转换电路的实现方法,并且已经在L波段某型通信系统中应用。

The transmit/receive channel is an important part of communication system all along.Especially with the development of digital integrated circuit（IC）,the analog circuit is replaced by high speed digital circuit step by step,so the high speed analog to digital/digital to analog（AD/DA）conversion circuit after transmit/receive channel becomes more important.This paper introduces a general realization method of high speed AD/DA conversion circuit,and the system has been already applied to a L-band communication system.
