A 5 GHz LC-VCO frequency synthesizer for unlicensed band of WiMAX

作者：

Highlights：

• Proposed and implemented a low power and low phase noise CMOS integer-N frequency synthesizer.

• A low phase noise of −121.1 dBc/Hz VCO is proposed and results in a better FOM.

• P counter only pulse swallow counter is proposed to low power consumption.

• High speed and low power TSPC counter is proposed.

• A successful chip fabrication and measurement of the proposed design.
