A fast-hopping frequency synthesizer that reduces complexity and power co㎱umption is presented for MB-OFDM UWB applicatio㎱. The proposed architecture uses 3960 ㎒ LC VCO, 528 ㎒ ring oscillator, passive mixer and LC-tuned Q-enhancement BPF to generate Band Group 1 frequencies. The adjacent channel rejection ratio is less than -40 ㏈c for 3432 ㎒ and -44 ㏈c for 4488 ㎒. A fast switching SCL-type MUX is used to produce the required channel output signal and it takes less than 2.2 ㎱ for band switching. The total power consumption is 47.9 ㎽ with a 1.8-V supply.
