N2 - A concise method for estimating the instantaneous current drawn by a microprocessor as a function of time is presented. The approach uses the measured output impedance to create an extrapolated, band-limited inverse filter which estimates the instantaneous load current from a highly averaged measurement of the output voltage. The algorithm is verified in simulation and measured results are presented.
