Résumé

Integrated circuit Hall sensor system comprising a plurality of elementary blocks (EB), each elementary block including a Hall cell (4), a differential pair (8) of an input stage of a Differential Difference Amplifier (DDA), and terminals (12a, 12b), wherein the terminals (12a, 12b) are placed laterally on opposing outer sides of each elementary block parallel to a Y axis and the plurality of elementary blocks are arranged in a juxtaposed manner to form at least one row (6a, 6b) extending along an X axis orthogonal to the Y axis and interconnected by the terminals.

Signalisation différentielle

La signalisation différentielle, ou transmission différentielle, est une méthode de transmission de signal électrique dans laquelle l'information est la différence entre les signaux transmis sur deux lignes. La transmission différentielle s'utilise aussi bien avec un signal analogique, comme en téléphonie, qu'avec un signal logique, comme en informatique. Elle permet de diminuer la sensibilité aux interférences. Au lieu de transmettre le signal comme tension par rapport à la masse, on utilise deux conducteurs, l'un convoyant le signal, et l'autre son inverse.

Differential amplifier

A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs. It is an analog circuit with two inputs and and one output , in which the output is ideally proportional to the difference between the two voltages: where is the gain of the amplifier. Single amplifiers are usually implemented by either adding the appropriate feedback resistors to a standard op-amp, or with a dedicated integrated circuit containing internal feedback resistors.

Plurality voting

Plurality voting refers to electoral systems in which a candidate(s), who poll more than any other counterpart (that is, receive a plurality), are elected. In systems based on single-member districts, it elects just one member per district and may also be referred to as first-past-the-post (FPTP), single-member plurality (SMP/SMDP), single-choice voting (an imprecise term as non-plurality voting systems may also use a single choice), simple plurality or relative majority (as opposed to an absolute majority, where more than half of votes is needed, this is called majority voting).
