Abstract

This paper presents a CMOS cross-coupled film bulk acoustic resonator (FBAR) oscillator which was designed in class-C topology in order to improve phase noise and power consumption. The designed class-C FBAR oscillator shows lower phase noise with the same power consumption than that of a comparatively designed class-B FBAR oscillator. The efficient current generation in class-C leads to the improvement. The designed FBAR oscillator exhibits a phase noise of -154.7 dBc/Hz at 1 MHz from carrier frequency with a total power consumption of 1.21 mW and a figure-of-merit (FoM) of 220 dB.
