Abstract :
A differentially tuned VCO is fully integrated in a standard microprocessor 0.12 μm SOI CMOS. A phase noise of -101.8dBc/Hz at 1MHz offset is measured with 7.5mW at 1.5V. The VCO tuning range is 9.8% from 40GHz to 44GHz. The output power is up to -6dBm after a single-stage buffer amplifier with 6mW at 1.5V.
