Claim 16:
17. An integrated circuit, comprising:
first and second doped regions both having a first conductivity type formed in a semiconductor substrate having a second conductivity type;
first, second, third and fourth terminals connected to the first doped region, the first and third terminals defining a first conductive path through the first doped region and the second and fourth terminals defining a second conductive path through the first doped region, the second conductive path intersecting the first conductive path;
fifth, sixth, seventh and eighth terminals connected to the second doped region, the fifth and seventh terminals defining a third conductive path through the second doped region and the sixth and eighth terminals defining a fourth conductive path through the second doped region, the fourth conductive path intersecting the third conductive path;
a first coil over the first doped region, and a second coil over the second doped region, the first coil configured to direct a current over the first doped region in a clockwise direction, and the second coil configured to direct the current over the second doped region in a counterclockwise direction; and
a shallow trench isolation layer between the first doped region and a surface plane of the semiconductor substrate.
