Abstract :
In this paper a reconfigurable differential Ultra Wideband-Impulse Radio (UWB-IR) energy receiver architecture has been simulated and implemented in UMC 90nm. The signal is amplified, rectified and integrated. By using an integration windowed scheme the SNR requirements are relaxed increasing the sensitivity. The design has been optimized for large bandwidths, low implementation area and configurability. The RX can be adapted to work at different data rates, processing gains, and channel environments. It works between the 3.1 - 4.8 GHz bands with OOK or PPM modulation with a tunable data rate up to 33Mb/s. In order to relax the ADC sampling time an interleave mode of operation has been implemented. It has a maximum power consumption of 22m W with a power supply of 1V. The complete RX occupies an area of 1.11mm2.
