Abstract
Electromagnetic noise source of an integrated circuit (IC) can be approximately modeled with three dipole moments. To improve the previous dipole moments extraction method using 3 TEM cell measurements data, a new dipole moments extraction technique using 24 measurements data in a GTEM cell is proposed herein. The nonlinear least square (NLS) method is applied to accurately extract the three dipole moments including the relative phases of each dipole moment. The near-magnetic field patterns calculated using the improved dipole moments extraction method are compared with those using the previous method.
