Abstract :
A tunable ultra-wideband (UWB) pulse generator is designed and simulated with standard 0.18 mum CMOS technology. By using a voltage controlled delay line (VCDL) technique, the proposed UWB pulse generator can adjust the pulse width, adding flexibility for use with different UWB applications. Moreover, each peak of the proposed UWB pulse is separately controlled so that it complies with the FCC regulation. The proposed UWB pulse generator achieves the fifth-order derivative of the Gaussian pulse and can tune the pulse width from 0.38-ns to 4-ns. In particular, the maximum and minimum pulse widths comply with 3-10 GHz and sub-GHz FCC regulations, respectively
