A single chip frequency synthesizer compliant with the ZigBee standard is designed in a standard 0.18? CMOS process. Integer N topology is chosen for the implementation. Synthesizer consists of third order passive loop filter; a CML based programmable frequency divider, a standard tristate PFD, a switch on source topology based charge pump and an on chip quadrature VCO. Simulated settling time is 300?sec. Synthesizer consumes 22mW of power at supply voltage of 1.8V and occupies an active area of mm².
