Abstract :
Thermal finite element method (FEM) calculations and SPICE-based dynamic thermal models are used to simulate and optimize the static and dynamic performance of miniaturized oven-controlled crystal oscillators (OCXOs). FEM can be used to generate the values of the SPICE circuit elements. Good agreement is achieved between simulation and measurement. Several application examples, including directly heated OCXOs, are discussed.
