Abstract :
This paper presents the design and the exploratory measurements of a fully integrated VCO for 5.2 GHz applications. The presented circuit is implemented in 0.35 μm SiGe BiCMOS technology from TSMC. The current drawn from 2.5 V is 19mA for the VCO. It has a tuning range of 900 MHz with a control voltage from 0 to 2 V. The measured phase noise is -108.6 dBc/Hz at 1 MHz offset from the 5.2 GHz, and a figure of merit of-166.15 dBc/Hz were obtained. The measured output power at 5.2 GHz are -18.8 dBm.
