A Temperature-Stable Film Bulk Acoustic Wave Oscillator

This letter reports a passively temperature-compensated CMOS oscillator utilizing a film bulk acoustic resonator. The resonator exhibiting an f ldr Q product of 2-4 X 10 12 s -1 is composed of molybdenum, aluminum nitride, and a compensation material that has a positive temperature coefficient of Yo...
