DESIGN OF CURRENT-MODE LOW-PASS FILTER WITH LEAPFROG STRUCTURE
具有跳耦结构的电流模式低通滤波器设计

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.
