Abstract:
1. A rotational angle sensor comprising: a first sensor integrated circuit including a first magnetic sensing portion, a first computing portion and first connecting terminals, wherein the first magnetic sensing portion and the first computing portion are connected to each other by the first connecting terminals; and a second sensor integrated circuit including a second magnetic sensing portion, a second computing portion and second connecting terminals, wherein the second magnetic sensing portion and the second computing portion are connected to each other by the second connecting terminals, wherein the first magnetic sensing portion is inclined at an angle of approximately 90 degrees with respect to the first computing portion toward a rear side of the first computing portion, wherein the second magnetic sensing portion is inclined at an angle of approximately 90 degrees with respect to the second computing portion toward a front side of the second computing portion, and wherein the first sensor integrated circuit and the second sensor integrated circuit are disposed such that the rear side of the first computing portion is opposite the front side of the second computing portion, and such that the first magnetic sensing portion and the second magnetic sensing portion overlap with each other.
