Effects of capacitors non-idealities in un-even split-capacitor array SAR ADCs
(Institute of Electrical and Electronics Engineers, 2016)
This paper studies the effects of capacitors non-idealities in the performance of un-even split-capacitor SAR ADCs. Also, election of the m and l bits of MSB and LSB capacitors banks, respectively, is studied to reduce ...

BandPass Sigma-Delta Analog-to-Digital Converters
(Springer, 2003)
The principle of ΣΔ Modulation (ΣΔM) is extended in BPΣΔMs to bandpass signals, especially but not only, with a narrow bandwidth. Thus, BPΣΔMs have much in common with their lowpass counterparts - whose properties have ...

Non-ideal quantization noise shaping in switched-current bandpass ΣΔ modulators
(Institute of Electrical and Electronics Engineers, 1999)
This paper presents a systematic analysis of the major switched-current (SI) errors and their influence on the quantization noise shaping of SI BandPass SD Modulators (BPSDMs). Closed form equations are provided for the ...

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, ...
