Highly adjustable mixer-based UWB pulse generator architecture with leakage compensation integrated in 40 nm CMOS

A novel highly flexible mixer-based ultra-wideband (UWB) pulse generator is designed. The baseband pulse generator has a controllable pulse width between 200 ps and 8 ns, while the output amplitude only varies over 80 mV in this entire range. The mixer is adjustable so that the voltage controlled oscillator leakage can be controlled and minimised. The proposed architecture gives a highly flexible UWB pulse generator for which the characteristics can be adjusted to fit the specifications of different applications and the spectral mask of the country/region of usage.
