If you use a current-feedback amp with the circuit in Figure 1, the amplifier's closed-loopbandwidth depends less on the closed-loop gain and the number of input channels.
如果使用如图1电路的电流反馈放大器，放大器闭环带宽较少的依靠闭环增益和输入通道数。

An improved algorithm is presented based on generalized predictive control, which enhances the stability and robustness of closed-loop systems, and realizes the fairness of bandwidth allocation.
The experimental and analytical results demonstrate that wide bandwidth, high voltage output and long-time stability can be achieved with power MOSFETs and a closed-loop scheme.
