Abstract

Recently, electromagnetic interference (EMI) and radiated emission have become a major problem for high speed circuit and package designers, Most of them are due to power and ground fluctuation. Decoupling capacitors have been mostly used to reduce the power/ground bounce of high-speed digital systems and boards. In this paper, we present a more powerful circuit model for power and ground bounce. This circuit reduces the power and ground bounce by the way of suppressing voltage increase through the resistance which varies with power fluctuation. We present numerical analysis and simulation data by comparing decoupling capacitors
