摘要:
本文提出一种电路,利用电流控制电流 conveyor 转导放大器(CCCCTAs)作为主动元件,可同时用作双极滤波器和振荡器。它使用两个CCCCTAs和两个电容器。作为双极滤波器,它可以在电压模式下实现所有标准滤波功能(低通、带通、高通、带阻和全通),并通过CCCCTAs的偏置电流实现极点频率和品质因子的电子和正交控制。所提出的电路也可以在不改变电路拓扑的情况下工作为振荡器。无需任何电阻器,仅使用电容器,所提出的电路适用于IC制造。通过PSPICE仿真验证了所提滤波器的有效性。
英文摘要:
In this paper, a circuit employing current controlled current conveyor trans-conductance amplifiers (CCCCTAs) as active element is proposed which can function both as biquad filter and oscillator. It uses two CCCCTAs and two capacitors. As a biquad filter it can realizes all the standard filtering functions (low pass, band pass, high pass, band reject and all pass) in voltage-mode and provides the feature of electronically and orthogonal control of pole frequency and quality factor through biasing current(s) of CCCCTAs. The proposed circuit can also be worked as oscillator without changing the circuit topology. Without any resistors and using capacitors, the proposed circuit is suitable for IC fabrication. The validity of proposed filter is verified through PSPICE simulations.
