The present invention generally relates to a system and method for high accuracy temperature control of an oven used to operate an electronic device, sensor or resonator (“device”) at a fixed temperature. The fixed temperature operation may result in high stability and operation accuracy of the devices across varying environment temperature conditions. Specifically, the present invention relates to systems and methods that enable realizing, sensing, and controlling the temperature of an ovenized device with high temperature control, accuracy, relaxed temperature sense, and control electronics requirements.
