A new filter operating in voltage mode and realizing all-pass function is proposed. The circuit requires a single current conveyor with an extra voltage input buffer stage and a floating capacitor, enjoys electronic tuning, needs input interface for easy connection and benefits by low output impedance, hence is load-insensitive and operable at twice the frequency range in comparison to other related circuits. In-depth theoretical and simulation studies are presented in support of the newly designed circuit.

电子调谐辅助输入接口支持负载不敏感滤波器，具有扩展频率范围

提出了一种在电压模式下工作并实现全通功能的新型滤波器。该电路需要一个带有额外电压输入缓冲级和浮动电容器的电流传输器，具有电子调谐功能，需要输入接口以便于连接，并受益于低输出阻抗，因此对负载不敏感并且可在两倍的频率范围内工作到其他相关电路。为支持新设计的电路，提出了深入的理论和仿真研究。
