Reduced complexity MASH delta-sigma modulator
Abstract
A reduced complexity digital multi-stage noise shaping (MASH) delta-sigma modulator for fractional-N frequency synthesizer applications is proposed. A long word is used for the first modulator in a MASH structure; the sequence length is maximized by setting the least significant bit of the input to “1;” shorter words are used in subsequent stages. Experimental results confirm simulations. © 2007, IEEE. All Rights Reserved.
