A programmable OOK impulse radio ultra wideband transmitter with power cycling and spectral agility

摘要

An on-off keying impulse radio ultra-wideband transmitter with frequency tuning ability based on a 0.13 µm CMOS process is presented. The output spectrum frequency and bandwidth can be adjusted using a digitally programmable oscillator in the 3.7 to 9 GHz range. This allows for the dynamic adjustment of the output spectrum to the surrounding environment. A fully integrated power cycling scheme is used to reduce significantly the power consumption. The transmitter achieves data rates of 10 Mbps with a simulated power consumption of 1.5 mW.
