    Abstract: The fabrication process comprises a phase of producing a base region having an extrinsic base and an intrinsic base, and a phase of producing an emitter region comprising an emitter block having a narrower lower part located in an emitter window provided above the intrinsic base. Production of the extrinsic base comprises implantation of dopants, carried out after the emitter window has been defined, on either side of and at a predetermined distance dp from the lateral boundaries of the emitter window so as to be self-aligned with respect to this emitter window, and before the emitter block is formed.

    Abstract: A symbol length is evaluated on the basis of receiving a first-symbol length, and a phase error with respect to detection of a length of the first symbol before receiving a length of a second symbol following the first symbol. The process includes evaluating at least two random phase errors on the basis of the phase error received. A first random phase error is dependent on a deterministic phase error with respect to a first state corresponding to an absence of a corrected first-symbol length. A second random phase error is dependent on a deterministic phase error with respect to a second state corresponding to the corrected first-symbol length. The process includes retaining as an evaluated symbol length the first-symbol length received if the absolute value of the first random phase error reduces a condition of passing through the first state. The second step also retains as an evaluated symbol length the corrected first-symbol length if the absolute value of the second random phase error reduces the condition of passing through the second state.

    Abstract: An integrated temperature sensor delivers threshold detection signals when temperature thresholds have been exceeded. The temperature sensor includes a circuit for detecting a first temperature threshold having a first detection threshold, and for detecting a second temperature threshold having a second detection threshold. The circuit also detects a third temperature threshold between the first and second temperature thresholds, and detects a fourth temperature threshold between the first and second temperature thresholds. The third temperature threshold has a third detection threshold linked with the first detection threshold so that a deviation of the first detection threshold causes a corresponding deviation of the third detection threshold. Similarly, the fourth temperature has a fourth detection threshold linked with the second detection threshold so that a deviation of the second detection threshold causes a corresponding deviation of the fourth detection threshold. The third and fourth temperature thresholds define a temperature window to test the temperature sensor for detecting a deviation of the first and second detection thresholds.
