Abstract :
In this paper the design of an oscillator based on active inductor (AI) is presented, and the advantages resulting from this approach in term of phase-noise reduction are illustrated. Replacing the inductor with the AI in a classical LC-resonator give significant advantages, due to the high quality factor of the AI and the corresponding high frequency-selectivity of the active resonator. As a proof of concept, three different oscillators at 2.35GHz have been designed, fabricated and tested. A comparison of the performances of a varactor-based resonator, an AI solution and a classical DRO configuration is carried out, showing the advantages of the proposed approach.
