请问你是如何理解电压反馈放大器和电流反馈放大器的？
附件的文章从多个参数性能对CFB和VFB进行了比较，可以参考下。
楼主可以参考下几点摘要和参考资料：
1. Unbalanced Input rather than Balanced Input ;
2. Open-loop gain units：Ω（transimpedance gain）rather then V/V;
3. The RF determines the overall frequency response;
很重要的一点，Rf决定了带宽和频率响应。
更多信息楼主可以参考这篇文档：《Voltage Feedback Vs Current. Feedback Op Amps》

再推荐一篇电流反馈运放的应用手册

电流反馈运放，主要关注输入极结构，反馈电阻。
