  • Process for tuning a magneto-resistive sensor
    Patent number: 5808273
    Abstract: A process for adjusting a magneto-resistive sensor having a pair of current contacts and a pair of voltage contacts to compensate an offset error, without additional components. The magneto-resistive sensor (10) is charged with a homogeneous, definitely oriented magnetic field, a defined control current (I) is applied between its current contacts (22, 24) and at least one of the voltage contacts (30, 32) is trimmed, for example, by a laser beam (38), during the measurement of a pseudo-Hall voltage across the voltage contacts.
