Abstract
In this paper some considerations on different oscillator topologies are presented with the aim of analyzing their behavior in terms of phase noise performance. In particular, our analysis suggests that a 9db improvement in the phase noise level can be obtained when using a “Push-Push” oscillator architecture in comparison with a fundamental-frequency oscillator developed under the same conditions. Simulations of different oscillator topologies, which confirm the proposed theory, are shown in the paper.
