数模转换器(DAC)在许多系统中得到应用,包括通信发射机和消费电子产品。在各种DAC实现中,电流舵拓扑提供最高速度,在千兆赫频率下成为事实上的解决方案,特别是在模拟输出必须输送到电阻负载的情况下。本文研究了该DAC的设计原理。
Digital-to-analog converters (DACs) find application in many systems, including communication transmitters and consumer electronics. Among various DAC realizations, the current-steering topology offers the highest speed and becomes the de facto solution at gigahertz frequencies, especially if the analog output must be delivered to a resistive load. In this article, we study this DAC's design principles.
