In this paper, a novel built-in tuning technique to compensate for variability induced imperfections in RF subsystems is proposed. The test stimulus is obtained from a filtered digital pattern and the RF response is down-converted using an envelope detector. The resulting signal is mapped to a digital signature, such that the Hamming Distance between the observed and the golden signature represents...
In this paper, jitter analysis algorithms for characterizing timing jitter of multi-Gbps pseudo-random bit sequences (PRBSs) are presented. For signal acquisition, incoherent sub-sampling is employed to increase the effective sampling rate of a digitizer and to simplify its signal acquisition architecture by removing the need for timing synchronization circuits. As a substitute for these circuits,...
