An application specific integrated circuit implementation of a multiple correlator for UWB radio applications

The Time Domain Corporation (TDC) has advanced their development of ultra wideband (UWB) technology to the point of having designed and produced an application specific integrated circuit (ASIC) solution for the correlator function in their UWB radio architecture. This paper describes the implementation of an ASIC multiple correlator for UWB radio applications up to 3.0 GHz. The topics covered include: an overview of UWB radio technology, typical UWB receiver system architecture, correlator requirements, implementation of the ASIC multiple correlator, preliminary performance data, and future developments.
