Magnetic field sensor - a device for the direct production of digital sensor data from a magnetic field sensor - element

摘要

Magnetic field sensor - device with:– a ring circuit (10, 50) comprising a plurality of semiconductor - magnetic field sensors (6) comprises, in the form of a ring are connected to one another; and– an output circuit (30) for detecting a speed of propagation of a pulse signal within the ring circuit (10, 50) during a predetermined time period and for the output of digital data (do1), which correspond to the thickness of a magnetic field acting on the basis of a detection result of the speed in the direction of propagation function;– each semiconductor - magnetic field sensor (6) source - areas (1a, 1b), drain - regions (2a, 2b) and a gate - electrode (3), in such a way that at least the drain - areas are divided, and the gate - electrode (3) channel regions (9) between the source - areas and the divided drain - areas is arranged, controls, wherein a number of charge carriers which, by means of the divided drain - areas of flow, in dependence on the thickness of the magnetic field to be exchanged, if the charge carriers, which flow through the channel regions, a magnetic field; and– one of the divided drain - regions of a preceding semiconductors - magnetic field sensor..
