摘要
提出了一种连续时间电压模式CCCII双二阶滤波电路。通过适当选取输入电压,可实现二阶低通、带通、高通、带阻和全通5种滤波功能。对电路进行了PSPICE仿真,仿真结果表明该电路正确可行。
The general circuit of a novel continuous-tlme vohage-mode CCCII biquadratic filter is presented. Using this filter, the second-order low-pass, band-pass, high-pass, notch and all-pass filtering functions can be realized with suitably chosen input voltage. The parameters of the circuit are adjusted independently and the circuit is simple. The simulation results are given to verify the theoretical analysis.
