    摘要: The invention relates to a magnetic field sensor comprising a substrate having a first side (S1). The substrate comprises at the first side (S1) a silicon comprising semiconductor layer (P-SUB) which comprises a buried N-well (DNW). A bipolar transistor having an emitter region (PE+, NE+), a base region (PB+, NB+), and a first collector region (CLR1) and a second collector region, is provided in the silicon comprising semiconductor layer (P-SUB). The emitter region (PE+, NE+) is located at the first side (S1) above the buried N-well (DNW). According to the invention the bipolar transistor is arranged such that, in operation, a part of an emitter current (IEM) that traverses the base region (PB+, NB+) is distributed over the first and second collector regions (CLR1, CLR2) obtaining a first and a second collector current (ICL1, ICL2), wherein a difference between the first and second collector currents (ICL1, ICL2) is determined by a magnetic field component (B x, B z ) perpendicular to a current plane. A bipolar magneto-transistor structure is obtained which is compatible with triple-well technology and that is sensitive to magnetic fields in a direction perpendicular to the current plane. The magnetic field sensor is compatible with triple-well technology and has a high linearity and a high sensitivity. The invention further relates to an integrated circuit comprising such magnetic field sensor (Snsr) and a card provided with such integrated circuit.

    摘要: The invention relates to a vertical Hall sensor in which an electroconductive region (2) extends into a substrate (1), perpendicularly to the surface of said substrate (1), in order to form a Hall sensor element (4), and comprises a plurality of first connection areas (3) along a lateral surface on the surface of the substrate (1). The inventive Hall sensor is characterised in that at least one second similar Hall sensor element (5) is arranged in the substrate (1) parallel to the first Hall sensor element (4), and is connected to the first Hall sensor element (4) in such a way that when the Hall sensor is operated according to the spinning current technique, the same combination of control current distributions is obtained in the Hall sensor in each spinning current phase. When the inventive vertical Hall sensor is operated according to the spinning current technique, it enables the offset to be significantly reduced without requiring a weighting of the individual spinning current phases.

On the surface (104) is arranged a central emitter structure (110, 210, 310) formed substantially mirror symmetrical with respect to a symmetry plane (106, 206, 306) that is substantially perpendicular to the surface (104, 204, 304), and a first and a second collector structure (116, 216, 316; 118, 218, 318), each of which is arranged spaced apart from the emitter structure (110, 210, 310) and which are arranged on opposite sides of the symmetry plane (106, 206, 306) so as to be substantially mirror images of each other. The first magnetic field sensor (100) is operated double-sided in that its first collector structure (116) and its emitter structure (110) are externally connected via a first read-out circuitry and its second collector structure (118) and its emitter structure (110) are externally connected via a second read-out circuitry. The second magnetic field sensor (200) is operated single-sided in that its first collector structure (216) and its emitter structure (210) are externally connected via a third read-out circuitry. The third magnetic field sensor (300) is operated single-sided in that its second collector structure (318) and its emitter structure (310) are externally connected via a fourth read-out circuitry.
