INTEGRATED CIRCUIT, COMPRISING A VOLTAGE CONTROLLED OSCILLATOR AND A METHOD FOR CONTROLLING A TEMPERATURE OF A VOLTAGE CONTROLLED OSCILLATOR

摘要

The invention relates to an integrated circuit, comprising at least a voltage controlled oscillator (VCO) for generating an output signal with an output frequency (f), where the voltage controlled oscillator (VCO) is arranged to be active during an active period, comprising a tuning period and an operation period following the tuning period. During the tuning period the output frequency (f) is tuned to a predetermined value. The integrated circuit further comprises at least one heating element (HE1, HE2, HE3, HE4) arranged to generate a heat flux, and a control unit (CU) arranged to control each at least one heating element (HE1, HE2, HE3, HE4). The control unit (CU) being arranged to control the heat flux generated by each at least one heating element (HE1, HE2, HE3, HE4) during the active period to control a temperature (TVCO) of the voltage controlled oscillator (VCO) during the operation period.
