Abstract
A resonator comprising a beam formed from a first material having a first Young's modulus and a first temperature coefficient of the first Young's modulus, and a second material having a second Young's modulus and a second temperature coefficient of the second Young's modulus, a sign of the second temperature coefficient being opposite to a sign of the first temperature coefficient at least within operating conditions of the resonator, wherein the ratio of the cross sectional area of the first material to the cross sectional area of the second material varies along the length of the beam, the cross sectional areas being measured substantially perpendicularly to the beam.
