摘要

提出了一种分数阶低通型频率滤波器的新解。提出的结构包括两个双输出电流跟踪器(DO-CFs)，两个多输出电流跟踪器(MO-CFs)和两个可调电流放大器(ACAs)。带通区和带阻区之间的过渡斜率可以通过有意控制由电阻值和ACA元件的电流增益变化给出的1到2范围内的顺序来调整。该建议得到了PSpice仿真的支持，该仿真使用了所用有源元件的晶体管级仿真模型。

A 1+α Low-Pass Fractional-Order Frequency Filter with Adjustable Parameters

A novel solution of a fractional order low-pass type frequency filter is presented. The proposed structure comprises of two Double-Output Current Followers (DO-CFs), two Multi-Output Current Followers (MO-CFs) and two Adjustable Current Amplifiers (ACAs). The slope of the transition between the band-pass and band-stop region can be adjusted by intentional control of the order in range from 1 to 2 given by the change of values of resistors and current gains of ACA elements. The proposal is supported by PSpice simulation using transistor-level simulation models of employed active elements.
