摘　　要：本文提出了一个用全平衡四端浮地零器实现的电压模式二阶通用滤波器结构,该电路具有多滤波功能、固有频率ω0独立调节、很低的无源灵敏度、低功耗、适合于模数混合集成电路、不用任何匹配就能实现全通功能等特点,PSPICE仿真证实了此电路结构的可行性。A configuration for realizing voltage-mode second-order multifunctional filter using fully balanced four-terminal floating nullor is presented in this paper.The proposed circuit owns many advantages,such as realizing multiple functions simultaneously , adjusting the natural angular frequency ω0 independently,lower passive sensitivities,lower power consumption,be suitale for mixed analog and digital circuits and realizing the allpass function under the condition that no matching condtion exists .PSPICE simulation results verify the circuit performance.
