The synthesizer, which is designed for use in the upper band of U-NII receiver, consists of a low power, high efficient voltage-controlled oscillator (VCO), and an injection-locked frequency divider (ILFD). The power consumption of the synthesizer is reduced by using an ILFD as the first frequency divider in the PLL feedback loop.
The frequency synthesizer can work in 5.650~5.876GHz that can synthesize 4 channels with every channel space is 20MHz. The total power consumption of the synthesizer is 34.02mW from a single 1.8V supply. It is only 8.37mW that the power is consumed by the VCO and the ILFD combined. The phase noise is -112dBc/Hz at 1 MHz offset. The synthesizer has a bandwidth of 500KHz for a 10MHz reference and the locking time is about 26us, which is suitable for the IEEE 802.11a WLAN applications.
