In this paper, a 3–5 GHz impulse radio ultra wideband BPSK transceiver is presented. A new all-digital architecture is applied in the proposed transceiver. The transceiver has no mixer and low complexity. The transmitter employs a RLC network response filter to achieve the adjustable pulse parameters, which includes pulse width, pulse bandwidth and pulse amplitude. Considering the low duty ratio,...
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...
A 3-5 GHz low power amplitude and spectrum tunable BPSK modulated impulse radio UWB transmitter is designed with SMIC 0.13 um CMOS technology. IR-UWB is a carrier-less system. It has the advantage of low power and low complexity, but it has difficulty in controlling the spectrum. In this design the amplitude and spectrum of the output impulse are both tunable to fix this problem. The simulation results...
