A Novel Integer-Bit Estimation Scheme in Digital Filters Based on Probabilistic Behavior of Signals in the Internal Nodes.

Accurate estimates of the maximum swing of internal nodes in digital filters are highly desired, which is translated into better implementation on hardware in terms of area, power, and reliability. In this brief, an accurate semi-analytical method for estimating the internal node swing is presented. We use multiple word length method in which the fractional and the integer word lengths are not the...
