An output buffer is provided, to which first and second input signals are applied and that delivers an output signal. The output buffer includes a second offset switching stage installed in cascade downstream from a first switching stage. The second offset switching stage generates control points shifted in time with respect to memory points.

The disclosure relates to an electronic circuit including at least one first and one second differential pair each including a plurality of transistors. All the transistors of said first and second differential pair are included in a single well.

Electronic circuit with transistors sharing one and the same well

A successive approximation analog/digital converter is provided, which includes a successive approximation register supplying a digital/analog converter, first means of comparing an input signal of the analog/digital converter to an output signal of the digital/analog converter delivering a first comparison signal, said successive approximation analog/digital converter being synchronised by a clock signal coming from a conversion clock. A method such as this includes dynamic adaptation of the conversion clock period based on at least one parameter.

Successive approximation analog/digital converter and associated integrated component and conversion method

The present invention relates to a device for generation of a reference electrical voltage. The device includes a first current generator outputting a current proportional to temperature. The first current generator comprises at least one operational amplifier and two branches in parallel, a first branch comprising a first current source and a first bipolar transistor, and a second branch comprising a second current source, a first resistance and a second bipolar transistor. A second current generator outputs a current conversely proportional to temperature. The device includes means of summating the currents so as to obtain a voltage independent of the said temperature, and means of reducing dependence of the current circulating in the said first branch on the value of the said first resistance. The reduction means comprises at least one second resistance with a non-adjustable value.
