Computation of Maximum Voltage Droop in Power Delivery Networks

Abstract

Computation of maximum voltage droop in power delivery networks is important for performance estimation. This paper proposes a methodology to predict the maximum voltage droop caused by current sources in ICs. We derive the analytical relations and analyze the error in the predicted voltage droop values. Furthermore, we consider the effect of current step rise time on the voltage droop along with error analysis. Results capture the error bounds for the analytical equations derived.INDEX TERMS Integrated circuit (IC), maximum voltage droop, power delivery network (PDN)
