本文提出用信号流图(SFG)设计有源C滤波器的方法。这种设计方法简捷。所设计的滤波器是对LC梯形的功能模拟。有源C滤波器优于有R源滤波器,更适于全集成实现。具有高频率和低灵敏度特性。文中也给出了低通设计实例。
This paper presents a method of designing an active C filter using Signal Flow Graph (SFG). This design method is simple. The designed filter is a functional simulation of the LC ladder. Active C filter is better than R source filter, more suitable for fully integrated implementation. High frequency and low sensitivity. The article also gives a low-pass design examples.
