Abstract :
A fully-integrated, ZigBee standard compliant, frequency synthesizer in the frequency range of 2.4-2.4835 GHz with frequency resolution of 5MHz, is designed in 0.18mum epi-CMOS process and silicon performance is measured. Integer-N architecture is chosen for implementation. It consumes 7.95mW of power at 1.8V supply and core area is 0.75times0.65mm2. The measured phase-noises are -81.55dBc/Hz and -108.55dBc/Hz at 100kHz and 1MHz offset, respectively, with low settling time less than 25mus
