FLIP-CHIP INTEGRATED OSCILLATOR WITH REDUCED PHASE NOISE AND ENHANCED OUTPUT POWER BY USING DGS
采用DGS降低相位噪声和提高输出功率的倒扣集成振荡器(英文)

A novel defected ground structure(DGS) was designed and applied to a flip-chip integrated millimeter wave oscillator.The characteristics of two oscillators with and without DGS were analyzed and compared.Measurement data shows that the phase noise of the oscillator with DGS is reduced by 4~6dB,and the output power of the oscillator is increased by 0.8dBm in comparison with the oscillator without DGS.It is found that,when DGS is embedded in the resonant tank and the output terminal of an oscillator,the phase noise can be reduced and the output power will be enhanced.
