摘要
提出两个三输入、单输出多功能电流模式滤波器,每个滤波器都由三个第二代电流传输器(CCⅡ)及一些接地电阻和电容组成。通过选择滤波器的输入端,即可在输出端得到低通、高通、带通、陷波和全通五种基本滤波功能。与同类文献[1,2]相比,不但电路简单,而且角频率ωn和品质因素Q可实现独立可调,无源灵敏度较低。同时,对其中的一种滤波器进行了硬件实现,并对滤波器的低通、高通和带通性能进行了测量和分析,充分证明了该滤波器的优良性能。
In this text, a current-mode filter sented, which is made of only three CC Ⅱ s, four circuit with three inputs and one output is pre grounded resistances （R） and two grounded capacitances. It can carry out second order low-pass, high-pass, band-pass, notch and all-pass filtering functions by selecting different inputs. The property of the circuit is testified by simulating using PSPICE software. Compared with the literature, it is simpler, and its center frequency and the quality factor can be adjusted separately, and it is more insensitive to R and C.
