Abstract :
A new low-cost, low-power fully integrated CMOS transmitter-antenna was designed, built and tested for UWB systems. The CMOS pulse generator can generate monocycle and impulse signals with tunable pulse duration. The UWB antenna is integrated directly with the CMOS chip. The antenna has less than 18- dB return loss and can transmit and receive UWB impulse signals over the entire UWB bandwidth of 3.1-10.6 GHz. The UWB transmit-antenna module can generate and transmit both monocycle pulses from 140 to 350 ps and impulses from 100 to 300 ps.
