摘要
提出了一新型三输入单输出电压模式滤波器电路.该电路能实现低通、带通、高通、带阻及全通等五种滤波器.该电路具有输入阻抗高、固有频率与品质因数独立可调、所有RC无源元件均接地及无源灵敏度低的特点.
The paper presents a new high-input impedance voltage-mode filter configuration with three inputs and one output based on CCII. The configuration can realize the second-order low-pass, band-pass, high-pass, notch and all-pass responses.Compared with the latest published voltage-mode filters with three inputs and one output,the new filter offers the following advantage features simultaneously: i)high impedance, ii)orthogonal control of nature frequency ω_(0) and quality factor, iii)grounding of passive elements. At last, we give the PSPICE simulation results which are in good agreement with the theoretical ones.
