| Abstract(in English) | This paper presents Q-factor simulation and SSB noise measurement for transmission line feedback FET oscillators By taking into account the FET parasitic elements, we simulated oscillation conditions, oscillation equilibrium stability predictions and Q-factor for three types of single loop feedback FET oscillators They have topologies 1) without open stub, 2) with an open stub at drain port and 3) topology with stubs at drain and gate ports To verify this simulation, we fabricated the circuits for these topologies and measure SSB noise As the result, the higher Q-factor oscillators exhibit lower SSB noise than that for lower Q-factor ones They agree with Leeson's formula with standard deviation of 0 17 dBrms. |
