The design procedure of a CMOS process integrating Colpitts cr(ystal oscillator is described in detail by using the tools of Matlab and advanced design system (ADS). The small-signal analysis is performed both in the viewpoint of negative resistance and positive feedback. The analysis of condition for reliable start-up of oscillation and design guides for low phase noise is introduced. The measured phase noise is (172dBc/Hz@10 kHz and the power dissipation i…查看全部>>
