摘要
首先阐明有源滤波器的基本概念和传递函数,然后着重介绍具有低灵敏度的GIC型双运放电路和在较高频率时应用的开关电容滤波器,最后举例说明它们的应用。
This paper presents an introduction to basic concept and transfer function of filter. And then GIC double OPA filter with low sensitiveness and switched capacitor filter used to higher frequency are emphatically discussed. And, some examples that account for applications are described.
