NEW STRUCTURE OF SC FILTERS WITH REDUCED GB EFFECT
减小SC滤波器中GB效应的新结构

In this paper, the problem how to reduce the GB effect in SC filter is discussed. A new general biquadratic SC structure in which the GB effect is reduced is developed. The structure is strays-insensitive, has very low Wo and Q sensitivities. Using the low-pass SC filter for example, the method of reducing GB effect has been shown in detail
