Abstract
A method of calibrating a first oscillator () is disclosed. A temperature is measured to obtain a measured temperature value and a determination is made of whether said measured temperature value differs from at least one previously measured temperature value by more than a threshold amount. If said measured temperature does differ from at least one previously measured temperature by more than said threshold amount, a reference oscillator () is used to calibrate the first oscillator ().
