A fully integrated multi-output CMOS frequency synthesizer for channelized receivers

A fully integrated frequency synthesizer that generates multiple frequencies for use in frequency channelized receivers is designed in 0.25 /spl mu/m CMOS technology. Many of the unique features of this receiver have been exploited to design a highly integrated and power efficient multi-output frequency synthesizer, including poly-phase filters. The synthesizer generates 4, 5, 6, and 7 GHz signals while dissipating 120 mW.
