通常生成电流源的方法是采用一线性调节器,该调节器的输出通过一已知的串联电阻反馈到可调整管脚。如果电流较小,或通过调节器的输入一输出电压差值不大,那么这就是一种较好的方法。如果电流或电压
The usual way to generate a current source is to use a linear regulator with the output of the regulator fed back to the adjustable pin via a known series resistor. If the current is small, or through the regulator input and output voltage difference is not big, then this is a better method. If the current or voltage
