Abstract

An oscillator circuit comprising at least a first component arranged to be statically calibrated to calibrate the oscillator circuit to achieve a symmetrical frequency/temperature profile for the oscillator circuit. The oscillator circuit further comprises at least one further component arranged to be dynamically calibrated to enable an oscillating frequency of the oscillator circuit to be dynamically adjusted, and at least one temperature compensation component arranged to receive at least one temperature indication for the oscillator circuit and to dynamically adjust the at least one further component based at least partly on the at least one received temperature indication. In some examples, the at least one temperature compensation component is arranged to dynamically adjust the at least one further component based on a standardized temperature compensation scheme.
