| 摘 要： | CIC滤波器作为一种高效的多采样器件,具有低通滤波的作用。它仅利用加法器、减法器和寄存器(无需乘法器),实现简单、成本低且速度高,因此被广泛应用。文章介绍了一种2～63倍内插率可编程的14位CIC内插滤波器的结构和特性,讨论了在设计中应注意的溢出保护、CIC通带补偿等问题。

| Abstract: | As an efficient low-pass filter for multiple rate change, CIC filter is widely used for its flexible, and multiplier-free structure. A design of 14-bit CIC programmable interpolator whose interpolation ratio can be any integer between 2 and 63 is introduced. Both of its economical structure and predictable characteristics are discussed, as well as a consideration for overflow protection, CIC compensation in pass band. |
