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。

When Sehat was 12, he taught himself analog signal processing by taking apart his family's Philips six-transistor radio and rebuilding it one component at a time.
