Background Digital Calibration of Comparator Offsets in Pipeline ADCs
(Institute of Electrical and Electronics Engineers, 2015)
This brief presents a low-cost digital technique for background calibration of comparator offsets in pipeline analog-to-digital converters (ADCs). Thanks to calibration, comparator offset errors above half the stage ...

On-chip characterization of RF systems based on envelope response analysis
(Institution of Engineering and Technology, 2010)
A simple on-chip procedure for testing embedded RF blocks is presented. It is based on the detection and spectral analysis of the two-tone response envelope of the device under test (DUT). A main difference with similar ...

Random chopping in ΣΔ modulators
(2009)
Σ∆ modulators make a clever use of oversampling and exhibit inherent monotonicity, high linearity and large dynamic range but a restricted frequency range. As a result Σ∆ modulators are often the preferred option for ...
