本文提出了一种无乘法器结构的级联积分梳状补偿滤波器。利用系数的最小误差逼近实现了一个二阶线性相位滤波器。补偿器滤波器系数以规范的有符号数字形式呈现。所提出的设计可以使用低成本的硬件单元，如添加和移位操作来实现。结果表明，补偿滤波器不仅降低了功耗，而且改善了CIC滤波器的通带压降。
This paper presents a cascaded integrator comb compensator filter with a multiplierless implementable structure. A second order linear phase filter is realized with minimum error approximation of the coefficients. The compensator filter coefficients are presented in a canonical signed digits form. Presented design can be implemented using low cost hardware units such as add and shift operations. The results show that the compensator filter not only reduces the power consumption but also improves the pass band drop of the CIC filter.
