    The invention concerns microelectromechanical resonators. In particular, the invention provides a resonator comprising a support structure, a doped semiconductor resonator suspended to the support structure by at least one anchor, and actuator for exciting resonance into the resonator. According to the invention, the resonator comprises a base portion and at least one protrusion extending outward from the base portion and is excitable by said actuator into a compound resonance mode having temperature coefficient of frequency (TCF) characteristics, which are contributed by both the base portion and the at least one protrusion. The invention enables simple resonators, which are very well temperature compensated over a wide temperature range.
