Abstract :
In this paper, a fully integrated CMOS UWB transmitter for impulse system is presented, including a Gaussian pulse generator, a driver amplifier and a LC bandpass filter. In the pulse generator, a delay line with thermal insensitivity is used to generate the impulse with rising time independent of temperature. The transmitter is implemented in Chartered 0.18-μm RF CMOS technology. The experiment results show that a Gaussian pulse of 150 mV peak-to-peak voltage amplitude is generated. The PSD of output pulse is below -41.3 dBm/MHz in 3.1 GHz~10.6 GH, at repetition frequency of 50 MHz. It fits the FCC requirement well.
