电流模式n阶OTA-C滤波器的设计

The Design of a CurrentMode NthOrder OTAC Filter

提出了设计电流模式ｎ阶ＯＴＡ－Ｃ滤波器的新方法：使用单端输入、双端输出的电流放大器及单端输入、三端输出的电流积分器对ｎ阶电流传递函数的信号流图进行综合，可实现ｎ阶低通、高通。

A new technique for currentmode nth order OTAC filter is presented, in which a currentmode amplifier with two outputs and currentmode integrators with three outputs are employed to synthesize the signal flow graph of the current nth order transfer function,in order to realize nthorder lowpass,bandpass and other filters. The design technique for the device is described and an example is given to illustrate the novel technique.
