Spur-Free MASH Delta-Sigma Modulation

IEEE Transactions on Circuits and Systems I: Regular Papers, 2010
For multistage noise-shaping (MASH) delta-sigma modulation, this paper presents a new structure that is free of spurs for all input values. The proposed MASH structure cascades several first-order delta-sigma modulators (DSMs) like the traditional MASH structure but has an additional feedforward connection between two adjacent stages. The proposed MASH

A digital modulator with bandpass delta-sigma modulator

Proceedings of the 30th European Solid-State Circuits Conference, 2004
A digital quadrature modulator with a bandpass ??-modulator is presented that interpolates orthogonal input carriers by 16 and performs a digital quadrature modulation at carrier frequencies fs/4, ?fs/4 (fs is the sampling frequency). After quadrature modulation, the signal is converted into an analogue IF signal using a bandpass ??

Effects of bandpass sigma-delta modulation on OFDM signals

IEEE Transactions on Consumer Electronics, 1999
This paper presents a behavioural analysis of bandpass OFDM signals sampled and quantized by means of a sigma-delta A/D architecture. It describes the direct effects of sigma-delta modulation on OFDM signals with a variable number of subcarriers by ...

Behavioral modeling of delta–sigma modulators

Computer Standards & Interfaces, 1998
Abstract This paper presents an overview of DelSi, a MATLAB toolbox developed for the design and simulation of delta–sigma modulators. The DelSi toolbox can synthesize a stable noise-transfer function for complex network structures. The modelling tool consists of two c / c ++ programs, sdMod.c, a single stage delta–sigma modulator and firfilt.c, a

Delta-sigma modulation in single neurons

2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003
In this paper we investigate the relationship between the pulse-coded signal representation found in biological neurons and signals represented by first-order delta-sigma bit-streams. We show that a first-order delta-sigma bit-stream is a digital equivalent to a pulse-coded neural signal.
