Ultra-low power transmitter

This paper presents a design of an ultra-low power UWB transmitter based on 4^th and 5^th derivative Gaussian pulse shapes implemented in UMC 90nm CMOS technology. The simulations show 119mV peak to peak pulse amplitude and the pulse width of 240 ps for the 5^th derivative Gaussian pulse and 99.71mV pulse amplitude and 190 ps pulse width for the 4^th derivative Gaussian pulse. Power consumption of the pulse generators are calculated 30.11 uW and 21.5 uW for the 5^th and 4^th derivative Gaussian pulse respectively at a 100MHz pulse repeating frequency (PRF). Ultra-low power radio transmission is important in such application contexts as wireless network nodes and sensors powered by energy harvesters.
