ASIC Implementation of Highly Reliable IR-UWB Transceiver for Industrial Automation

An in-depth treatment of impulse an radio ultra-wideband (IR-UWB) wireless system is provided reviewing theoretical background, proceeding with detailed implementation procedure, and finally giving simulation and test results. This is the first research and prototyping work to be published in the field of IR-UWB that operates in the 6-8 GHz band. The aim of this work is to implement an IR-UWB wireless system for industrial automation that is robust and reliable. To achieve this, an analogue bandwidth of 250 MHz and digital baseband processing at the clock frequency 499.2 MHz were realized in a 250 nm BiCMOS process, integrating the complete system into a single chip. Simulation and measurement results confirm that the implemented IR-UWB transceiver is operational across four frequency channels in the band 6-8 GHz each supporting three data rates 850 kb/s, 6.81 Mb/s and 27.24 Mb/s.
