Abstract :
A fully integrated CMOS impulse-based transmitter with on-off keying (OOK) modulation scheme, for ultra- wideband (UWB) impulse radio (IR) system has been designed in a standard TSMC 0.18 mum CMOS technology. A novel Gaussian mono-pulse generator using simple and robust design method has been presented. On-chip pulse shaping using LC Band-Pass Filter (BPF) is developed to meet the Federal Communications Commission (FCC) spectrum requirement. The proposed UWB transmitter has been laid out and post-layout simulation results are analyzed. A Gaussian mono-pulse of less than 100 ps falling/rising time with a 130 mVpp amplitude was observed, at a clock frequency of 500 MHz. The total power dissipation of the transmitter is 1.2 mW with only 316 muW consumed by impulse generator. The output of the transmitter is 48 mVpp under a 1.2 V power supply.
