中文摘要：
提出了一种基于多输出电流传输器（MO—CCII）的电流模式二阶通用滤波器，该滤波器具有3个输入端和1个输出端，通过选择不同的输入信号组合即能获得低通、高通、带通、带阻和全通5种滤波函数．电路结构简单，中心频率和品质因数独立可调，无源元件全部接地，滤波器特性参数对无源元件灵敏度低．理论分析和spice仿真表明该电路设计方案正确可行．
英文摘要：
A new second-order universal active current-mode filter based on MO-CCII is presented. The filters have one output and three inputs. Each kind of filter such as low-pass, high-pass, band-pass, notch and all-pass filter can be obtained by selecting the corresponding input signal combinations. The proposed circuit is with simple structure, separately adjustable centre frequency and the quality factor, all grounded passive components and low passive sensitivities. Theoretical analysis and spice simulation indicate that the proposed circuit is effective and feasible.
