Abstract :
This paper presents a reconfigurable 0.13 μm CMOS impulse radio ultra-wideband transmitter which supports the on-off keying modulation scheme. The transmitter allows for control of the center frequency and bandwidth of the output spectrum, thus providing large spectrum flexibility. A power cycling scheme is implemented to reduce the power consumption, and allows the system to operate within stringent power requirements. The transmitter achieves data rates of 100 Mbps with a maximum simulated power usage of 506 μW, while respecting the FCC radiated emissions limits. The UWB spectrum can be adjusted from 7.3 to 8.3 GHz, with pulse width ranging from 0.8 to 1.8 ns.
