This thesis presents a low power consumption and low phase noise CMOS integer-N frequency synthesizer, and it bases on a charge-pump PLL topology. The frequency synthesizer can be used for IEEE 802.16b unlicensed band of WiMAX(World Interoperability for Microwave Access) from 5.725GHz to 5.825GHz. It provides the one ration frequency ranged from 5.13GHz to 5.22GHz for the local oscillator in RF front-end circuits. The proposed frequency synthesizer consists of a phase-frequency detector, a charge pump, a low-pass loop filter, a voltage-controlled oscillator, and a pulse-swallow divider. In system design, we present the new architecture for voltage-controlled oscillator to achieve low power consumption and low phase noise. Moreover divider is implemented by an optimal extended true single-phase clock-base prescaler. It can achieve high-resolution frequency operation and reduction of power consumption. This chip is fabricated in a TSMC 0.18£gm CMOS 1P6M technology process. The whole chip area is 1.1 mm2.
