New simple digital self-calibration technique for pipeline ADCs using the inter...
Goes, J.; Paulino, N.; Evans, G.; Figueiredo, M.IEEE International Symposium on Circuits and Systems, pp. 232 – 235, Seattle, EUA ; This paper describes a new digital-domain selfcalibration technique for high-speed pipeline A/D converters using the internal thermal noise as input stimulus. This lowamplitude noise is amplified and recycled by the ADC itself and, due to the successive foldings, it is naturally converted into uniform noise. This noise is then ...

Efficient digital self-calibration of video-rate pipeline ADCs using white gaus...
Ortigueira, M.D.; Unterweissacher, M.; Goes, J.; Paulino, N.; Evans, G.Proceedings of IEEE, ISCAS 2003, Vol.I, pp. 877-880 ; A digital-domain self-calibration technique for video-rate pipeline A/D converters based on a white Gaussian noise input signal is presented. The implementation of the proposed algorithm requires simple digital circuitv. An application design example of the self-calibration of a IZb. 40 MUS CMOSpipeline ADC is shown to illustrate that the overall linearity ...
