Abstract :
Conventional metal wiring is becoming an inevitable difficulty for a computing platform. This paper presents an Ultrawideband (UWB) wireless interconnection solution. The channel characteristics within a computer chassis is analyzed, including the path loss, multipath reflections and electromagnetic interferences (EMI). To address the above problems, an IR-UWB transceiver is proposed with equalization in transmitter to relax the multipath reflections and pulse injection-locking for receiver clock recovery and synchronization. The transceiver achieved a significant power saving for high data rate (up to 500Mbps) demodulation.
