Excessive power supply noise increases propagation delay of switching gates and reduces noise margin of the circuit. Adding on-chipdecouplingcapacitors(decaps) is an effective way to reduce voltage noise in a on-chip power delivery *** this paper,we propose an efficient and novel algorithm to allocate decaps in an area efficient *** new algorithm applies the sequence of linearprogramming based approach to searching the minimum decap area to reduce voltage drop below user specified *** show existing sensitivity based decap allocation algorithms tend to over estimate the decap areas due to nonlinear sensitivity dependence on decap *** results show that the proposed algorithm uses significantly less decap area than the existing conjugate gradient based approach but with similar CPU runtimes.
