A CMOS low complexity Gaussian pulse generator for ultra wideband communications

A Gaussian pulse generator is proposed for UWB impulse radio systems. The generator is probed in two modulation schemes (PP and BPSK) transmitting at 400 Mbps. The proposed modulators are coupled to a 50 ohms load. The Gaussian pulse generator has been designed and simulated in Mentor Graphics for a TSMC 0.18 um MMRF CMOS process with a power supply of +/-0.9 v.
