Abstract

A new transmitter for ultra-wideband (UWB) impulse radio is described in this paper. The new UWB transmitter implements a low power Gaussian shaping filter to reduce the side-lobe in the frequency domain. A simple pulse amplitude modulation (PAM) circuit is used to keep the power consumption low. The proposed architecture features the simple design, low-power operation, and enables the pulse-shape generation for a multi-channel UWB. The core layout size is only 0.2 mm2. The simulation results show that the generated signals satisfy the FCC spectrum mask, and the average power consumption is
