Abstract

A new electronically tunable current-mode multifunction universal filter with three inputs and one output based on current-controlled current follower transconductance amplifier is presented. The proposed filter can realize low-pass, band-pass, high-pass, band-stop and all-pass filtering functions into single topology. For realize these filtering functions, no passive component-matching conditions, no inverting-type input signal requirements and high-output impedance are possessed. Also the proposed filter offers electronic control of the natural angular frequency, low active and passive sensitivities and use of grounded capacitors which is ideal for integrated circuit implementation. The proposed universal biquadratic filter has been used to realize sixth-order filters. PSPICE simulation results are used to confirm the presented theory.

采用电流控制电流跟随器跨导放大器的电子可调谐电流模式多功能滤波器

提出了一种基于电流控制电流跟随器跨导放大器的三输入一输出电子可调谐电流型多功能通用滤波器。该滤波器可在单一拓扑结构中实现低通、带通、高通、带阻和全通滤波功能。为了实现这些滤波功能，不需要无源元件匹配条件，不需要反相型输入信号和高输出阻抗。此外，所提出的滤波器提供了对自然角频率的电子控制，低有源和无源灵敏度，并使用接地电容器，这是集成电路实现的理想选择。所提出的通用双二次滤波器已用于实现六阶滤波器。PSPICE仿真结果验证了所提出的理论。
