Abstract
A temperature-compensated microelectromechanical oscillator and a method of fabricating thereof. The oscillator includes a resonator element including highly doped silicon and an actuator for exciting the resonator body into a resonance mode having a characteristic frequency-vs-temperature curve. The properties of the resonator element and the actuator are chosen such that the curve has a high-temperature turnover point at a turnover temperature of 85° C. or more. In addition, the oscillator comprises a thermostatic controller for keeping the temperature of the resonator element at said high turnover temperature.
