摘　　要：介绍了一种可编程双路二阶有源滤波器设计方法。该双路二阶有源滤波器主要由有源滤波器与可编程控制器两部分组成,可以实现低通、带通输出。应用厚膜混合集成工艺,研制样品可采用双电源供电,电压范围宽(±9V～±18V),参数指标满足使用要求。其结构简单,控制灵活,性能可靠,避免了传统滤波器电子元件多、不宜调节的缺点。A novel design method of programmed dual 2nd-order active filter is proposed, which is composed of active filter and prograrmned controller. The programmed filter can be not only a low-pass filter but also a band-pass output. The filter adopting hybrid integrated circuit techniques uses dual power supply which is from ±9V to ±18V. All of the parameters meet the needs. The falter architecture is simple and can be controlled flexibly, The results show the filter performance is reliable.
