Ultra-Low-Jitter Fully Tunable Baseband Pulse Generator for UWB Applications

A fully tunable baseband ultra-wideband pulse generator realized with commercial off-the-shelf components is presented. It is made of high-speed logic gates and comparators, and it is compliant with the current-mode logic digital standard. The pulse emitted power and bandwidth are tunable with pulsewidth and amplitude variation, which shows high flexibility. This advantage simplifies the design of the downstream shaping network, as so to be compliant with international regulations. A differential output with very low jitter is demonstrated.
