Low-power transmitter for UWB Impulse Radio

This paper proposes the use of pulsed UWB in the design of fully-integrated low-power radios for sensor node applications. A key-point is compliance with ETSI/FCC regulations on power spectral density, obtained through proper pulse selection and differential architecture. Instantaneous power consumption better then 6 mW and temperature stability may be possible using advanced 1.0 V 90 nm technology. Also temperature and process variation may be controlled by means of digital calibration techniques.
