摘　　要：提出了用信号流图法设计n阶基于OTA(跨导运算放大器)和CCII(第二代电流传输器)电流模式低通滤波器的方法。该滤波器由具有双输出端的平衡滤波器和第二代电流传输器及接地电容构成。与同类电路比较,设计更简便,结构更简单,无源元件全部接地,易于集成。A new way to design n-order OTA and CCII current-mode low-pass filter by signal flow graph is presented. The filter is constructed by OTA with a double output and CCII as well as grounded capacitors. Compared with similar circuit, the filter has the advantages of simpler and more convenient design. The circuits are easy to be integrated for all grounded capacitors.
