This paper introduces a highly configurable UltraWideBand (UWB), triangular wave, baseband pulse generator designed in 40 nm CMOS technology. The baseband pulse width is adjustable between 660 ps and 3.8 ns. An extra amplitude compensation loop is implemented to prevent amplitude changes when the pulse width varies. The amplitude variations are limited to 13 % compared to the maximum amplitude over the entire pulse width range. The amplitude compensation loop allows a pulse amplitude tuning range between 280 mV and 640 mV, while the pulse width only varies 80 ps over this entire range. The pulse generator has a maximum simulated signal to noise ratio (SNR) of 59 dB and a measured maximum power consumption of 6.2 pJ/pulse from a 0.9 V power supply and a 100 MHz pulse repetition frequency.
