| 摘 要： | 本文讨论了在开关电容(SC)滤波器中如何减少增益带宽积(GB)效应的问题,提出了一个减少GB效应的新的双二次拓扑结构,此结构对寄生电容不敏感,并且具有很低的无源W0,Q灵敏度。以低通SC滤波器为例,给出了减小GB效应的具体设计方法。并用设计实例和实验结果证明了所得结论的正确性。

| Abstract: | 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 |
