Abstract
Recent work with chip scale integrated FBAR oscillators has highlighted the fact that the temperature sensitivity is similar to SAW resonators. This sensitivity is significantly higher than quartz crystal oscillators, and limits the application of the technology. This investigation looks at the feasibility of stabilizing the frequency of the oscillator with a heater resistor and sensor resistor integrated into close proximity with the resonator, and an on-chip temperature feedback network.
