－βRC电流模式CCII双二次滤波器设计

CCII-BASED-βRC CURRENT-MODE BIQUADRATIC FILTER DESIGN

该文提出了一类新的电流模式双二次电路，它们仅包含－β电流放大器及ＲＣ器件．这些电路是通过对偶变换从Ｓａｌｌｅｎ－Ｋｅｙ等人的－ｋＲＣ电压模式双二次电路得到，电流放大器由ＣＣＩＩ构成．这些双二次电路可以直接级联起来．

A class of current-mode biquads uaing the-βcurrent amplifier and ROcomponents are presenced in this paper.They are derived directly from the Salled-Key-kRO voltage--mode biqnads by dual transformation.COil devices are uSedas convenient eurrent amplifiers here. These biquads can be cascaded directly.
