| Popis: |
We present a 22µW, 2.0GHz FBAR oscillator - the lowest power reported to date for a GHz-range oscillator of this type. Low power consumption is achieved through co-design with a high R p FBAR resonator and a weakly-forward biased bulk connection. An oscillator with a standard bulk connection was fabricated for comparison. The chip was fabricated in a 0.18µm CMOS process. The weakly-forward biased bulk led to a 41% reduction in power dissipation. The measured phase noise is −121dBc/Hz at a 100kHz offset. |
