Exact IC current extraction method using a measured voltage of a board

The key to designing power distribution network (PDN) is to obtain correct current drawn by integrated circuits (IC). This paper suggests an exact IC current extraction method using a measured voltage of a board and new transfer function which reflects the effects of the scope´s noise. Voltage waveform is measured at the location where the closest decoupling capacitor from an IC would be removed in a real structure. The proposed methodology is evaluated by comparing the simulated noise voltage from the extracted current with the measured one for a 1.2V core circuit.
