| Next » Temperature compensation of crystal oscillators using an Artificial Neural Network

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.
