Using sigma-delta A/D methods, high resolution can be obtained for only low to medium
signal bandwidths. This article describes conventional A/D conversion, as well as its …

Photonic-based A/D conversion has received and continues to receive considerable
attention as an alternative approach to providing enhanced resolution and speed in high …

In this paper, a method to design and implement a very efficient multistage decimation filter
for a sigma-delta (/spl Sigma//spl Delta/) A/D converter is proposed. The scheme is …

Coarsely quantized MIMO signalling methods have gained popularity in the recent
developments of massive MIMO as they open up opportunities for massive MIMO …

The analysis of the quantization noise in delta-sigma modulators is not a trivial task. State-of-
the-art analysis methods include modelling the quantization noise as a uniform distributed …

Conventional delta-sigma analog-to-digital converters (/spl Delta//spl Sigma/ADC's) are
widely used in low-bandwidth applications such as high-fidelity audio processing because …

We examine the uplink spectral efficiency of a massive MIMO base station employing a one-
bit Sigma-Delta (ΣΔ) sampling scheme implemented in the spatial rather than the temporal …

Systems containing both analog and digital functions have been investigated with the
purpose of realizing mixed-signal integrated circuits with higher levels of functionality and …

Parallelism can be used to increase the conversion bandwidth of delta-sigma (/spl Delta//spl
Sigma/) analog-to-digital converters (ADCs). Time-interleaved, parallel/spl Delta//spl Sigma …

In this paper, a comprehensive system behavioral model of frequency-interleaved analog-to-
digital converters (FI-ADCs) is presented. The model addresses mismatch errors due to …
