Power estimation of recursive and non-recursive CIC filters implemented in deep-submicron technology
Muhammad Yunus Hi Abbas, Oscar Gustafsson, Lars Wanhammar · 2010
The power modeling of different realizations of cascaded integrator-comb (CIC) decimation filters has been a subject of several recent works. In this work we have extended these with modeling of leakage power, which is an important factor since the input sample rate may differ several orders of magnitude. Furthermore, we have pointed out the importance of the input wordlength on the comparison of recursive and nonrecursive implementations.
