Abstract :
This paper describes a method for the optimal placement of the decoupling capacitors on the printed circuit board (PCB). This method searches the optimal position of decoupling capacitor so that the impedance characteristics at the power supply is minimized in the specified frequency range. In this method, the PCB is modeled by the PEEC method to handle the 3-dimensional structures and the Krylov-subspace technique is applied to obtain efficiently the impedance characteristics in the frequency domain
