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...
