摘要
设计了一种基于V/I转换电路的电流跟随器。对一种常见形式的V/I转换电路进行变形,得到一个存在一定系统误差的电流跟随器。通过对系统误差的分析,针对误差产生的主要因素提出了两种基于不同思想、不同形式的改进方案,得到两种改进型电路。理论推导、软件仿真及实际硬件电路测试都证明此方案合理可行。
The paper designs a current follower based on the V/I converting circuit. It obtains a current follower which has a certain system errors by transforming a common form of V/I converting circuit. Through the analysis of system error, the paper puts forward two improvement schemes based on different ideas, getting two improved circuits according to the main factors of errors. Theoretical deducing, software simulation and actual hardware circuit test all prove that the schemes are feasible.
