MATLAB/SIMULINK-Based High-Level Synthesis of Discrete-Time and Continuous-Time Sigma-Delta Modulators
(Institute of Electrical and Electronics Engineers, 2004)
This paper describes a tool that combines an accurate SIMULINK-based time-domain behavioural simulator with a statistical optimizer for the automated high-level synthesis of ΣΔ Modulators (ΣΔMs). The combination of high ...

Highly Linear 2,5-V CMOS ΣΔ Modulator for ADSL+
(Institute of Electrical and Electronics Engineers, 2004)
We present a 90-dB spurious-free dynamic range sigma–delta modulator (ΣΔM) for asymmetric digital subscriber line applications (both ADSL and ADSL+), with up to a 4.4-MS/s digital output rate. It uses a cascade (MASH) ...

Analysis of error mechanisms in switched-current Sigma-Delta modulators
(Springer, 2004)
This paper presents a systematic analysis of the major switched-current (SI) errors and their influence on the performance degradation of ΣΔ Modulators (ΣΔMs). The study is presented in a hierarchical systematic way. First, ...
