Abstract
This letter presents a fully integrated frequency synthesizer implemented in a 0.18-μm foundry CMOS process. By employing a modified differential Colpitts voltage controlled oscillator to improve the tuning range and the phase noise, the integer-N frequency synthesizer demonstrates an output frequency from 14.8 to 16.9 GHz, allowing wideband operations at Ku-band. Operated at an output frequency of 15 GHz, the proposed synthesizer exhibits a reference sideband power of -50 dBc and a phase noise of - 104.5 dBc/Hz at 1-MHz offset. The fabricated circuit consumes a dc power of 70 mW from a 2-V supply voltage. © 2007 IEEE.
