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: An operational amplifier may include a differential stage comprising two transistors whose gates are respectively linked to the two inputs of the operational amplifier. The sources of the two transistors may be linked to a first current source whose delivered current depends negatively on temperature variations and to a second current source whose delivered current is proportional to absolute temperature. The sum of these two currents may be less dependent on temperature, in that this link of the sources of the two transistors with the two current sources is effected respectively by way of two resistors, and in that the current which passes through the two transistors is imposed of proportional with temperature type, so as to allow substantially temperature-independent elimination of the offset voltage of the operational amplifier while obtaining a temperature-independent constant gain-bandwidth product.

Abstract: An electronic chip includes a shared strip with first and second spaced apart portions extending along a direction of elongation and an intermediate connecting portion extending between the first and second portions. The second portion is connected to a pad that has a greater surface area than the second portion. The first portion is formed by a first plurality of metallic strips. Metallic strips of the first plurality of metallic strips that are adjacent and side by side are separated by a distance smaller than a width of those metallic strips. The second portion is formed by a second plurality of metallic strips. Metallic strips of the second plurality of metallic strips that are adjacent and side by side are separated by a distance smaller than a width of those metallic strips.

Abstract: A method includes generation of a first current proportional to absolute temperature and formation of a second current representative of the temperature variation of the threshold voltages of the transistors of the inverter and limited to a fraction of the first current. This fraction is less than one. The inverter is supplied with a supply current equal to the first current minus the limited second current.

Abstract: Series of first ramps and second ramps are generated. A circuit delivers a first signal representative of the comparison of each first ramp with a set point and delivers a second signal representative of the comparison of each second ramp with the set point. Based on the first and second signals: a first ramp is stopped and a second ramp is started when the first ramp reaches the set point, and a second ramp is stopped and a first ramp is started when the second ramp reaches the set point. The value of the set point is modulated in response a maximum value of the first/second last ramp compared with the set point.
