摘要
A switched VCO-based UWB transmitter for 3-5 GHz is implemented using 0.18 mu m CMOS technology. Using RF switch and timing control of DPGs, the uniform RF power and low power consumption are possible regardless of carrier frequency. And gate control of RF switch enables the undesired side lobe rejection sufficiently. The measured pulse width is tunable from 0.5 to 2 ns. The measured energy efficiency per pulse is 4.08% and the power consumption is 0.6 mW at 10 Mbps without the buffer amplifier.
