基于LC梯形网络运算模拟的对数域滤波器设计

Log-domain filter design based on the operational simulation of LC ladders

介绍了一新颖的差分CMOS对数域积分器 ,给出了其系统传递函数 ,并以其作为一基本的对数域构建框 ,采用基于LC梯形无源滤波网络运算仿真的方法 ,设计了一三阶切比雪夫对数域滤波器 。

A new differential log-domain filter is introduced ,and its transfer function is given ,based on the log-domain building block.A third-order Chebyshev log-domain filter is designed by the technique of the operational simulation of LC ladders, and the simulated results are presented.
