Abstract
Decoupling capacitors are widely used to manage power supply noise [281] and are an effective way to reduce the impedance of power delivery systems operating at high frequencies [28, 29]. A decoupling capacitor acts as a local reservoir of charge, which is released when the power supply voltage at a particular current load drops below some tolerable level. Since the inductance scales slowly [129], the location of the decoupling capacitors significantly affects the design of the power/ground networks in high performance integrated circuits such as microprocessors. At higher frequencies, a distributed system of decoupling capacitors are placed on-chip to effectively manage the power supply noise [279].
