Abstract :
A dual-band frequency synthesizer with integrated VCOs has been designed and fabricated in commercial 0.25μm RFCMOS process for 2.4GHz 802.11 b/g applications. The RF side (2.1GHz) achieves -124 dBc/Hz phase noise performance at 1MHz offset and 0.9 degrees of integrated phase error. The IF side (750MHz) achieves -130 dBc/Hz at 1MHz offset and 0.4 degrees of integrated phase error. The power up to synthesizer ready time is 40μS for both sides. The synthesizer has been implemented to a single-chip 802.11b/g RF transceiver. Bench testing has demonstrated excellent performance at 802.11g 54Mbps/64QAM operation mode.
