摘要

提出了一种基于电压型DVCC的多功能双二次滤波器结构。该电路使用两个dvcc作为有源元件，以及两个电容器和三个电阻作为无源元件。该滤波器可在单电路中实现低通、高通、三通、带消和全通响应。新的配置提供非常高的输入阻抗，这使得易于级联和享受低灵敏度。利用CMOS实现的DVCC，通过PSPICE仿真验证了理论结果。

DVCC based voltage-mode multifunctional biquadratic filter

A voltage-mode DVCC based multifunctional biquardratic filter configuration is proposed. The circuit uses two DVCCs as active elements and together with two capacitors and three resistors as passive elements. The proposed filter can realize the low-pass, high-pass, three band-pass, band-eliminate and all-pass responses in a single circuit. The new configurations offer very high-input impedance, which enables easy cascading and enjoy low sensitivities. The theoretical results are verified with PSPICE simulations using a CMOS realization of DVCC.
