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.
