Popis:	In this paper, an open looped fast automatic frequency calibration (AFC) unit used in 2.4GHz CMOS integer-N phase-locked loop (PLL) frequency synthesizer (FS) for IEEE802.15.4/ZigBee wireless sensor networks (WSN) is presented. The calibration method accomplishes efficient search for an optimum discrete tuning curve of the voltage controlled oscillator (VCO) among a group of frequency sub-bands. The pre-simulation, layout design and post-simulation results are given. Post simulation results show that the AFC performs well.
