This paper presents a complete noise analysis of a ΣΔ-based fractional-N phase-locked loop (PLL) based frequency synthesizer. Rigorous analytical and empirical formulas have been given to model various phase noise sources and spurious components and to predict their impact on the overall synthesizer noise performance. These formulas have been applied to an integrated multiband WLAN frequency sy...

SMT solvers have recently been extended with techniques for finding models in presence of universally quantified formulas in some restricted fragments. This paper introduces a translation which reduces axioms specifying a large class of recursive functions, including well-founded (terminating) functions, to universally quantified formulas for which these techniques are applicable. An empirical ...

Constrained counting is important in domains ranging from artificial intelligence to software analysis. There are already a few approaches for counting models over various types of constraints. Recently, hashing-based approaches achieve both theoretical guarantees and scalability, but still rely on solution enumeration. In this paper, a new probabilistic polynomial time approximate model counte...
