    Abstract: A method is used to control an electronic device that includes a switching unit having a main MOS transistor having a substrate, a first conducting electrode and a second conducting electrode coupled to an output terminal. The method includes controlling the main transistor in such a way as to put it into an on state or an off state such that, when the main transistor is in the on state, the substrate and the first conducting electrode of the main transistor are connected to an input terminal and, when the main transistor is in the off state, the first conducting electrode of the main transistor is isolated from the input terminal and a first bias voltage is applied to the first conducting electrode and a second bias voltage is applied to the substrate of the main transistor.

    Abstract: A method is provided for controlling a sample and hold circuit that includes a switching module coupled to a storage capacitor. A circuit external to the sample and hold circuit of generates at least one main current representative of at least one leakage current of the switching module in its off state. The at least one main current is delivered to at least one auxiliary capacitor. An initial pulse signal is generated from the charging and discharging of the at least one auxiliary capacitor. The sampling phase of the sample and hold circuit is triggered at the rate of the pulses of a pulse signal derived from the initial pulse signal.

    Abstract: A calibration method of a temperature sensor is provided. The temperature sensor having a current source and a ring oscillator generating a square pulse signal with a temperature-dependent square pulse frequency. The acquisition of a first square pulse frequency measurement at a first temperature from the square pulse signal forms a first measurement point. A second square pulse frequency measurement at a second temperature from the second square pulse signal forms a second measurement point. The determination of the relation data being representative of an affine relation between square pulse frequency measurements and temperatures. The affine relation being defined by a used proportionality coefficient modified with respect to a measured proportionality coefficient of a measured affine relation linking the first measurement point and the second measurement point.
