一、引言迄今为止,数-模变换器均需要有电阻解码网络,例如权电阻网络、T 型网络等。电阻网络的作用是通过阻值的选择和网络的结构使某一标准量(如恒压源的电压或恒流源的电流)受数字系统的控制并
I. INTRODUCTION So far, digital-to-analog converters require a resistor decoding network such as a resistor-resistor network and a T-network. The purpose of a resistor network is to control a certain standard amount (such as the voltage of a constant voltage source or the current of a constant current source) by the digital system through the choice of resistance and the structure of the network
