Abstract: A semiconductor device includes a substrate, two first voltage-to-current converters and two second voltage-to-current converters. The substrate includes four layout regions arranged in an array having a plurality of columns and a plurality of rows. The array is line-symmetrical with respect to a first axis and line-symmetrical with respect to a second axis, wherein the first axis perpendicularly intersects the second axis at an array center point of the array. The two first voltage-to-current converters are respectively arranged in two of the four layout regions, wherein layouts of the two first voltage-to-current converters on the substrate are point-symmetrical with respect to the array center point. The two second voltage-to-current converters are respectively arranged in the other two of the four layout regions, wherein layouts of the two second voltage-to-current converters on the substrate are point-symmetrical with respect to the array center point.

Abstract: A semiconductor device includes a substrate, two first voltage-to-current converters, two second voltage-to-current converters and two third voltage-to-current converters. The substrate includes six layout regions arranged as an array having a plurality of columns and a plurality of rows, the array is line-symmetrical with respect to a first axis and a second axis which are perpendicularly intersected at an array center point of the array. The two first voltage-to-current converters, the two second voltage-to-current converters and the two third voltage-to-current converters are respectively arranged in the six layout regions. With respect to the array center point, layouts of the two first voltage-to-current converters are point-symmetrical, layouts of the two second voltage-to-current converters are point-symmetrical, and layouts of the two third voltage-to-current converters are point-symmetrical.
