Decimation for Sigma Delta Modulation
IEEE Transactions on Communications, 1986Decimation is an important component of oversampled analog-to-digital conversion. It transforms the digitally modulated signal from short words occurring at high sampling rate to longer words at the Nyquist rate. Here we are concerned with the initial stage of decimation, where the word rate decreases to about four times the Nyquist rate.

A Different View of Sigma-Delta Modulators Under the Lens of Pulse Frequency Modulation [Feature]
IEEE Circuits and Systems Magazine, 2023The fact that VCO-ADCs produce noise-shaped quantization noise suggests that a link between frequency modulation and Sigma-Delta modulation should exist.

Digital Filters for Sigma-Delta Modulation in Wireless Communications
International Semiconductor Conference, 2019This paper presents the effect of digital filtering in a sigma-delta modulation (SDM) used in wireless communications. SDM is widely used in digital-to-analog conversion because it offers high signal to noise ratio and distortion rate and low power and ...
