Patent ID: 7459906

Claim:
A semiconductor magnetic sensor for detecting a magnetic flux density of a magnetic field applied from an outside, comprising: a hall element formed in one of a square shape and a rectangular shape, for performing magnetoelectric conversion; a first transistor formed on a side of one side of the hall element, for driving the hall element, the first transistor having a drain connected to a first terminal formed on the one side of the hall element and having a source connected to a power supply terminal; a second transistor formed on the side of the one side of the hall element, for driving the hall element, the second transistor having a drain connected to a second terminal formed on the one side of the hall element and having a source connected to the power supply terminal; a third transistor formed on a side of another side opposite to the one side of the hall element, for driving the hall element, the third transistor having a drain connected to a third terminal formed on the another side of the hall element and having a source connected to a ground terminal; and a fourth transistor formed on the side of the another side of the hall element, for driving the hall element, the fourth transistor having a drain connected to a fourth terminal formed on the another side of the hall element and having a source connected to the ground terminal.
