Design of a Novel TH-UWB Signal Generator Based on 0.18-μm CMOS Process
A novel time-hopping ultra wideband (TH-UWB) signal generator is designed for TH-UWB communications.The generator consists of a 4-GHz oscillator and a switch with CMOS transmission gates.Through controlling the low frequency signals with time-hopping pulse position modulation (TH-PPM),the circuit outputs TH-UWB signals with wavelets.Implemented in 0.18-m CMOS technology,the generator provides the amplitude of 65mV at 50 load from a 1.8-V supply,and can directly drive an antenna by a transmission line.Meanwhile,the output impedance is matched to 50.The simulation results indicate that the performance of the generator is good and meets the standard of IEEE 802.15.3a.
