Among analog-to-digital converters, the delta-sigma modulator has cornered the market on
high to very high resolution converters at moderate speeds, with typical applications such as …

Continuous-time (CT) delta-sigma modulators (/spl Delta//spl Sigma/M's) suffer from a
problem not seen in discrete-time (DT) designs, that of excess loop delay: nonzero delay …

The performance of continuous-time (CT) delta-sigma modulators (/spl Delta//spl Sigma/M's)
suffers more severely from time jitter in the quantizer clock than discrete-time designs. Clock …

Excess loop delay (ELD) is well known for its detrimental effect on the performance and
stability of continuous-time sigma-delta modulators. A detailed analysis on the most recently …

Thoroughly revised and expanded to help readers systematically increase their knowledge
and insight about Sigma-Delta Modulators Sigma-Delta Modulators (SDMs) have become …

This paper presents the design strategy, implementation, and experimental results of a
power-efficient third-order low-pass ΣΔ analog-to-digital converter (ADC) using a continuous …

A methodology for analysis and synthesis of lowpass sigma-delta (/spl Sigma//spl Delta/)
converters is presented in this paper. This method permits to synthesize/spl Sigma//spl …

This paper introduces a possible compensation for finite gain-bandwidth (GBW) induced
errors in continuous-time sigma-delta modulators. Therefore, a novel model is derived which …
