This is done in the analog realm by wiring a transistor in a certain way.
在模拟世界里，这是通过以某种方式连接的晶体管来做到的。

Thus, each transistor of the current mirror (100) defines a step of the digital to analog conversion circuit, and the ratio between adjacent steps is substantially constant.
因此，电流镜(100)的每个晶体管限定数字模拟转换电路的步，相邻步之间的比率实质上是常数。
