摘要： The present disclosure relates to a method for controlling a device comprising an oscillation circuit, configured to provide a clock signal to a radio frequency circuit, and an antenna, in which the enabling of the passage of the signal from the circuit to the antenna is delayed with respect to an instant from which a power amplifier of the circuit is enabled.

摘要： A quartz crystal resonator is coupled to an electronic circuit. A capacitive or resistive element is provided for adjusting a frequency of the quartz crystal resonator on activation or deactivation of a function of a circuit. Control is made according to a model of an expected variation of a temperature of the quartz crystal resonator.

摘要： A quartz crystal resonator is connected to an array of switchable capacitors or resistors. The switched actuation of elements of the array is controlled by bits of a control word. At least one of the bits of the control word is controlled by pulse width modulation to effectuate a tuning of the oscillation frequency of the quartz crystal resonator.
