The Future of Temperature-Compensated Crystal Oscillators by John Esterline Published by Circuit Cellar Magazine, October 2014 Most modern digital and analog electronic devices require a time base to perform their intended function. Found in everything from cell phones to smart munitions, quartz crystal oscillators are widely used in many embedded applications. Quartz resonators’ high Q, excellent temperature performance, and superior long-term aging makes them the clear resonator of choice for many applications. The frequency versus temperature performance of a discrete LC oscillator will be on the order of several hundred parts per million (ppm) per °C, where a crystal oscillator (XO) will have roughly ±30 ppm over the entire industrial temperature range (–40 to +85°C). While being superior to a discrete oscillator, this temperature stability is not nearly sufficient for many modern applications...

Through the use of an Artificial Neural Network (ANN), temperature compensation of AT cut crystal oscillators can be achieved with better than +/-10ppb stability over the industrial temperature range (-40 to +85 °C). This is more than a 10 fold improvement over state of the art polynomial function generator compensation.
