Abstract :
A fully integrated 3.2 to 4 GHz frequency synthesizer, part of an IEEE 802.11a/b/g transceiver, is implemented in a 0.25 μm standard CMOS technology. The phase noise is -105 dBc/Hz at 10 kHz offset, and the spurs are below -64 dBc when measured at the 5 GHz transmitter output. The settling time is less than 150 μs.
