本文提出了一种改进型Howland电路的增强型。输出阻抗最大可提高二倍。文中给出了理论推导，包括从双端口网络角度进行的分析，并且使用通用运算放大器进行的仿真和实验结果证实了预期结果。
In this paper, an enhanced version of the improved Howland circuit is proposed. An improvement in output impedance to a maximum factor of two is obtained. The theoretical derivation is presented, including analysis from a two‐port network perspective, and both simulation and experimental results using a general purpose opamp confirm the expected result.
