Abstract
A fully integrated 5-GHz PLL frequency synthesizer for WSN applications has been designed and implemented in 0.18μm CMOS technology. With automatic current calibration technique (ACC), the VCO could maintain a good performance under a small current consumption of about 0.3mA. Phase switching technique is used in the frequency divider to reduce power consumption. Using a 1.8V supply voltage, the measured power consumption is 12mW and the phase noise is -111.13dBc/Hz at 1MHz offset.
