A non-coherent FSK-OOK UWB impulse radio transmitter for clock-less synchronization

Clock-less synchronization and data recovery can be achieved with FSK-OOK modulation and demodulation in non-coherent UWB impulse radio (UWB-IR) system. In this work we report a 30 Mbps non-coherent FSK-OOK UWB-IR transmitter. The chip is fabricated with 0.25 µm Silicon on Sapphire (SOS) process. The chip size is 1 mm by 1mm with pad. The power consumption with 2.5 V supply is 30mW. A graphic user interface was developed to control the power and frequency of the transmitter as well as the data rate of the test-bench.
