Abstract
Techniques related to a digital filter include at least one decimator disposed between an integrator section and a comb section such that the transfer function of the filter has split zeros. The resulting filter implementation employs considerable less silicon real estate than other prior art implementations with spread zeros, and has more design flexibility with improved resulting performance than the Hogenauer implementation.
