Abstract :
A 1-V 5.2-GHz CMOS frequency synthesizer for WLAN 802.11a transceivers is implemented in a 0.18-/spl mu/m standard CMOS technology. A novel design technique is proposed to achieve a 1-V 5.2-GHz low-power programmable frequency divider for the synthesizer. At a 1-V supply, the synthesizer measures a phase noise of -136 dBc/Hz at a 20-MHz frequency offset and a spurious tone of less than -80 dBc while dissipating 27.5 mW and occupying a total core area of 1.03 mm/sup 2/.
