A 22µW, 2.0GHz FBAR oscillator

Abstract

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 Rp 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… (More)
