Abstract: A power supply system includes a voltage application source, and a switched mode power supply having an output coupled to the voltage application source through a first path and through a second path different from the first path. A first node is coupled to the output of the switched mode power supply, the switched mode power supply being configured to couple the first node to the voltage application source through the first path in a first operating mode and through the second path in a different second operating mode. A digital regulator is coupled to the first node. A digital circuit is coupled to an output of the digital regulator. An analog regulator is coupled to the first node and an analog circuit coupled to an output of the analog regulator.

Abstract: 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.

Abstract: 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.
