Abstract :
In this paper, we report a low power integrated circuit that implements an adaptive version of the cross-correlation derivative algorithm for the estimation of inter-aural time difference. The architecture and logic structure as well as measured results reporting the performance of the IC -fabricated in a standard CMOS 0.5 mum process - are shown.
