There is an error in the opening paragraph of section 2 and the accompanying figure 1. The sentence that states: The magnetization directions of each half bridge element are opposite to each other and this doubles the bridge output compared with that of the single sensor as well as providing for improved temperature stability (Popovic et al 1996). should read: The barber pole patternings of each half bridge element are opposite to each other and this doubles the bridge output compared with that of the single sensor as well as providing for improved temperature stability (Popovic et al 1996). The magnetizations and current directions are incorrectly drawn in figure 1. These are corrected in the figure 1 shown in the pdf file.
