Abstract :
In this paper, a fully integrated CMOS UWB transmitter is presented. The transmitter consists of a band-notched UWB antenna and a transmitter IC which integrates a pulse generator, a gating signal generator and driver amplifiers. The drive amplifier employs a 2-stage amplifier-a class-E amplifier and a class-A amplifier with switch control, to significantly reduce power consumption. Fabricated using a 0.18-mum CMOS process, the generated pulse is then passed through the driver amplifier (DA) which not only drives the antenna but also shapes the generated digital pulse in the FCC spectral mask.
