As data transmission rates and signal frequencies continue to escalate, so do the design challenges to address Signal Integrity (SI) and Power Integrity (PI) problems. For PI, verifying that adequate power can be delivered to components is crucial, as the inability to do so can result in intermittent board failure and hours troubleshooting in the lab. This instantaneous power demand is often addressed by incorporating decoupling capacitors. Analyzing the associated loop inductance can help designers achieve a balance where inductance is minimized and capacitance is maximized to create a stable and reactive power delivery network.
This eBook answers the following questions:
- What are the major obstacles to meeting your board’s high-frequency power demands?
- What are the effects of loop inductance on your PCBA Power Delivery Network (PDN)?
- What are the limitations to following capacitance rules of thumb for selection and placement?
- How you can determine, fix, and improve loop inductance?
- How you can use signal integrity and power integrity simulation tools to optimize decoupling capacitor utilization and achieve the reactive (capacitive and inductive) balance that improves your board’s PDN.
