具有跳耦结构的电流模式低通滤波器设计
DESIGN OF CURRENT-MODE LOW-PASS FILTER WITH LEAPFROG STRUCTURE
-
摘要: 本文讨论了电流模式RC梯形结构低通滤波器的一种有源实现方法跳耦法,以此实现的电流模式低通滤波器采用CCⅡ,CCⅠ器件做为有源器件,比相应电压模式电路结构简单,且RC元件全部接地。这种跳耦结构和梯形结构一样具有低的元件灵敏度。

Abstract: Leapfrog technique is discussed and used to realize current-mode lowpass active RC ladder structure. The current-mode lowpass filter realized by this method only takes CCII, CCI as active devices, and all RC elements axe grounded, therefore, this structure is simpler than the relating voltage-mode one. It also has low sensitivity as the other ladder structures do. -
