摘 要: 根据n阶带通滤波器传递函数的特点和低通与高通级联的思想,给出了高阶RC有源带宽可调的带通滤波器的一般设计方法和VCVS结构电路的设计步骤,并成功设计出一款高性能的四阶有源带通滤波器,其电路简单,通频带宽,精度高,成本低廉。经Multisim10仿真测试,其性能完全达到了预期效果和设计要求。 According to the characteristic of n - order band - pass filter transfer function, the idea of cascading low- pass and high- pass filter was took in the paper, which presented an ordinary designing method of higher - order RC active band width adjustable band - pass filter and the designing procedure of VCVS structural circuit. Finally a high - powered fourth - order band - pass filter, which is simply circuit, wide pass band and high precision, less cost, was successfully designed. The performance is theoretically satisfied with the need of the design through the Muhisim 10 simulation test.
