Power-efficient CTBV symbol detector for UWB applications

In this paper, we present a novel symbol detector architecture using time-domain running cross-correlation intended for impulse radio UWB communication. A bold new perspective on system design processing (CTBV) completely in continuous time is proposed and an implementation is carried out in 90 nm TSMC low power process technology. By exploring CTBV coding and unique combinational circuits for signal processing operations, a fast and power efficient solution is found to be feasible for clockless CMOS implementation.
