通用高阶OTA－C滤波器的信号流图实现

The Realization of a Universal High Order OTA-C Filter Based On Signal-Flow-Graph

以传递函数的信号流图实现为基础，设计了一种新的通用高阶可调ＯＴＡ－Ｃ滤波器；这种滤波器只需要ＯＴＡ器件和接地电容，适合于ＭＯＳ技术集成。计算机模拟结果表明了它的可行性。

A new general tunable high-order OTA-C filter based on a signal-flow-graph realization of the transfer functions is designed. The filter needs only OTAs and grounded capacitors and is convenient for being realized by MOS technology. Computer simulation results are given to show its feasibility.
