1. An integrated circuit comprising first and second inductor arrangements, wherein:

  • each said arrangement comprises four inductors adjacently located in a group and arranged to define two rows and two columns,the integrated circuit is configured to cause two of those inductors diagonally opposite from one another to produce an electromagnetic field having a first phase, and to cause the other two of those inductors to produce an electromagnetic field having a second phase, the first and second phases being substantially in antiphase,the first and second phases of the first inductor arrangement are substantially in quadrature with the first and second phases, respectively, of the second inductor arrangement,each said inductor arrangement defines associated null lines along which its effective electromagnetic field has zero or negligible field strength, andthe first and second inductor arrangements are each located substantially along one of each other'"'"'s said null lines.
