Abstract
A system and method of making an apparatus for managing heat distribution in an oscillator system is disclosed. In an example embodiment, the apparatus includes a resonator configured to provide a periodic signal, a circuit coupled to the resonator configured to compensate for changes in the periodic signal due to variation in temperature, and further includes a heat source configured to generate heat that heats the resonator and the circuit. At least one of the resonator, circuit, and heat source is embedded in a substrate, and the resonator, circuit, and heat source are arranged to heat the resonator and circuit substantially the same amount.
