Abstract

A method of calibrating a first oscillator (102) 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 (108, 110) is used to calibrate the first oscillator (102).
