A novel mixed analogue/digital design of a phase picking algorithm in an oversampling clock phase recovery is presented. The proposed approach results in reduced processing time, improved integrability with analogue front-end and low noise generation. Simulations of a 10 Gbit/s burst-mode clock phase alignment circuit in a 0.25 mm SiGe BiCMOS process, show a simulated processing delay of only 280 ps.

A new embedded ranging system in the ISM band is described. The proposed indoor ranging system combines the advantages of both broadband and narrowband signals to achieve high ranging accuracy in the presence of strong multipath reflections to achieve a good link budget and to be compliant with spectral regulations. The system is based on a WLAN transceiver (with embedded ranging specific circuits) and uses the same frequency band for both communication and ranging purposes so that no separate dedicated ranging transceiver is needed. A prototype has been implemented to evaluate the performance of the proposed technique in a realistic environment. Experimental results show ranging accuracies of less than 20 cm.
