| Abstract |
This paper analyzes a technique for selecting decoupling capacitors to maintain a stable power supply in a power distribution network. It analyzes the effect of decoupling capacitors in the frequency domain of the power distribution network and calculates the target impedance for placing the capacitors. To solve the problem of the original decoupling capacitor placement, the capacitor value was selected using the equivalent series resistance of the capacitor. The effectiveness of the proposed method when selecting decoupling capacitors in a power distribution network is verified through simulation. |
