A modeling platform for efficient characterization of phase-locked loop /spl Delta/-/spl Sigma/ frequency synthesizers

By Taoufik Bourdi, Assaad Borjak and Izzet Kale

Abstract

The aim of this paper is to determine the stability of higher-order /spl Delta/-/spl Sigma/ modulators using the describing function method. The maximum stable input limits for third-, fourth- and fifth-order Chebyshev Type II based /spl Delta/-/spl Sigma/ modulators are established. These results are useful for optimising the design of higher-order /spl Delta/-/spl Sigma/ modulators
