Abstract:
A device comprising: a voltage reference supply, configured to provide a reference voltage that varies in response to temperature according to a predefined relationship; a temperature sensor providing a temperature signal indicating a temperature; a first controller configured to receive the temperature signal and to output a control signal; an LC-DCO receiving the reference voltage and providing an output signal with a frequency from an LC circuit, the LC-DCO comprising a switched capacitor bank configured to provide temperature compensation by varying an effective capacitance in the LC circuit in response to the control signal.
