- 초록
- A multi-LO frequency synthesizer block for MB-OFDM UWB systems is proposed, which is implemented in 0.18 μm CMOS technology. The proposed frequency synthesizer can provide three LO tones and quadrature IF LO tone from only one VCO. Based on an optimized frequency plan, it uses fewest nonlinear components like divide-by-N and mixer to suppress unwanted spurious tones. Its measured in-band sideband suppression ratio is more than 30 dBc for three sub-bands and it consumes only 17.6 mA from a 1.8 V supply. © 2006 IEEE.
