|Abstract:||This work addresses the design of an impulse-based ultra-wideband transmitter targeting short-range radio systems in the 3-10 GHz band. In this paper we describe the complete transmitter at circuit level, from baseband data input up to the antenna interface. To ensure the output signal fits within the FCC-UWB spectrum mask, the transmitter comprises nearly independent tuning structures and supports multi-modulation formats. The proposed circuits have been designed in a mixed-signal/radio-frequency CMOS 90-nm process. Post-layout simulation results are presented, including several process corners, which further demonstrate the ability of the transmitter to proper compensate for parameter deviations.|
