Thermal compensation (TC) has long been the problem for accurate time keeping. During the mechanical era of horology, the problem was consider solved with the invention of alloys with high dimensional stability vs temperature. Invar is one such alloy, Charles Édouard Guillaume won the Nobel prize for physics for his work on Invar. The current industry standard is to strap a TC ASIC to a single crystal oscillator. But other methods have been used in the past. For example, a carefully designed...
