| Abstract: | This brief describes the design of a frequency synthesizer for 2.3/4.6-GHz wireless applications in a 0.35-/spl mu/m digital CMOS process. This synthesizer provides dual-band output signals by means of frequency doubling techniques. Output frequency of the proposed synthesizer ranges from 1.87-2.3 GHz, and 3.74-4.6GHz. This chip consumes a total power of 80 mW from a single 2-V supply, including 45 mW for dual-band output buffers. Core size is 2200 /spl mu/m/spl times/1600 /spl mu/m. |
