其设计特点是采用了共源共栅电流镜，运放的输出作为驱动的同时还作为自身的偏置电路；其次是采用了带隙温度补偿技术。

The cascade current mirror was used in the circuit, and the output of the OPAMP was used for the bias of itself and to drive the next stage.

如果可能的话，不要使用偏置补偿(脉冲电流)。因为对脉冲电流的感抗可能会使测量不稳定，或者使自动量程功能难于工作。

If possible, do not use offset compensation (pulsed current) because inductive reaction to the current pulse may cause unstable measurements or make autoranging difficult.
