The relationship between the controlvoltage and the current output by the constant-current source may shift.
控制电压和由恒流电源输出的电流之间的关系改变可能会产生漂移。

A fairly basic circuit (left as an exercise, but it's not difficult) can take the controlvoltage and output a constant current which is proportional to the voltage.
一个相当基础的电路(留作练习，不过并不难)处理控制电压并输出与电压成比例的恒流。
