摘要

本文提出了一种新型的双输入四输出电压型通用双二次型滤波器。该滤波电路仅使用一个差分电流传送带跨导放大器(DDCCTA)和四个无源元件。该电路可以提供低通(LP)、带通(BP)、带阻(BS)、高通(HP)和全通(AP)双二次函数。固有角频率(ωo)和质量因子(Q)可以通过调整电路元件进行正交调谐。所提出的配置具有低分量计数和低主动和被动灵敏度。采用0.5 μm MIETEC CMOS工艺参数进行了PSPICE仿真，验证了理论预测。

Voltage-mode universal biquadratic filter using a single DDCCTA

In this paper, a novel two-input four-output voltage-mode universal biquadratic filter is presented. The filter circuit uses only one differential difference current conveyor trans-conductance amplifier (DDCCTA) and four passive components. The circuit can provide low-pass (LP), band-pass (BP), band-stop (BS), high-pass (HP), and all-pass (AP) biquadratic functions. The natural angular frequency (ωo) and the quality factor (Q) can be orthogonally tuned by adjusting the circuit components. The proposed configuration has a low component count and low active and passive sensitivities. PSPICE simulations with 0.5 μm MIETEC CMOS process parameters are given to confirm the theoretical predictions.
