A high performance current-reused CMOS LC-voltage-controlled oscillator (LC-VCO) for WiMAX communication and internet application is fabricated in TSMC 0.18-µm CMOS process. The proposed VCO applies the complementary cross-coupled technique and uses differentially tuned accumulation MOS varactors. Measured results achieve 27.86% frequency tuned range when biased between 0–1.8 V, tunable output frequency...
