Error Analysis of Approximate Ripple Borrow Subtractors

Abstract:

In this article, we study the output error in terms of the delay of the arithmetic subtractor circuit. By the formal analysis the borrow in arithmetic subtractor, especially the borrow chain, we model the discrete signals in the continuously, then construct the output error model and energy consumption model of the ripple borrow subtractor circuit. With these models, we do the trustable analysis formally.
