摘 要:An ultra broadband fractional-N frequency synthesizer for 802.11a/b/g zero-IF transceiver application is *** mathematical models for the behavior of the synthesizer's spur and phase noise are analyzed,and the optimization methodology is *** results exhibits that the frequency synthesizer's integrated phase noise is less than 1°(1 kHz to 100 MHz)with a 4.375 GHz carrier(after divide-by-2),and the reference frequency spur is below-60 dBc operating with a 33 MHz reference *** frequency synthesizer is fabricated on a standard 0.13μm RF CMOS process and consumes 39.6 mW from a 1.2 V supply voltage.
