Abstract :
This paper presents two gm-boosted VCOs. One VCO is built with Si MOS field effect transistors. The second one is built with SiGe bipolar transistors. Both VCOs are designed to cover a large tuning range from 5.2 GHz to 5.9 GHz and to minimize the power dissipation. Measured results for both oscillators are shown. Finally the performance of both oscillators is compared and analyzed.
