Abstract [en]

This paper presents a transmitter design for Ultra Wideband Impulse Radio (UWB-IR) communications. The design is targeted towards the implementation of passive Wireless Sensor Tags (WST) where micro-power consumption is required. The transmitter has been implemented in UMC 0.18μm CMOS and placed inside a QFN lead-less package. It complies with the FCC regulations for Pulse Rate Frequencies (PRF) up to 10MHz using OOK modulation. It is capable of adjusting the Power Spectral Emissions (PSE) modifying the transmitted pulse amplitude to always achieve the best BER/Power performance depending on the application demands. The power emission tunability has been validated implementing a complete communication link using a low sensitivity non-coherent energy receiver. Measurements show a maximum power consumption of 92uW@10MHz PRF having a maximum energy/pulse of 9.2 pJ.
