Abstract: For power delivery applications, a method for reducing impedance is through the addition of decoupling capacitors (decaps). In this article, we propose a knowledge-based optimization method to determine decap design in power delivery networks (PDNs).
The key focal-point for this paper is the optimization of PDN decoupling capacitor networks for high-performance and high-reliability systems where performance and robustness are the primary considerations. When working with complex PDNs most engineers rely on simulation software to assist in the design.
The Power Delivery Network (PDN) performance is measured by extracting of the Printed Circuit Board (PCB) 3 parameters, DC resistivity, capacitor loop inductance and target impedance decoupling.
The power supply is designed to regulate output voltage at the DC bulk voltage which is reached after the HOLD-UP time. If a HOLD-UP time is required, there are tradeoffs with respect to the power supply design input voltage and regarding the size of bulk capacitors.
Processor packages also incorporate decoupling capacitors, typically around the edges and on the underside. Lastly, processors use a variety of on-die capacitors; these are the closest to the active circuits and provide the fastest response times to transients. Figure 2.
