Optimizing a Decoupling Capacitor on a PCB: A Fully Time-Domain Approach Based on PSO and TD-CIM

In this paper we propose an efficient methodology for finding the optimal position and value of a decoupling capacitor on a printed circuit board (PCB). The solution procedure is carried out entirely in the time domain and it is based on a Particle Swarm Optimization (PSO) algorithm in combination with the Time-Domain Contour Integral Method (TD-CIM). The introduced method is tested on four illustrative problem scenarios.
