With the energy-saving of devices and the low voltage of ICs, the use of DC/DC converters with excellent conversion efficiency is increasing. In recent years, DC/DC converters have become very frequently used due to improvements in several drawbacks, including high performance, high functionality, miniaturization, and reduction of external components. However, to effectively utilize them, it is important to minimize noise generation and reduce the impact of generated noise on other circuits. Therefore, assuming that the selection of peripheral components considering noise has been adequately done, we will verify "how much noise countermeasures can be achieved through substrate patterning" with practical examples. *For detailed content of the article, please refer to the related links.

This document is a "PCB Noise Mitigation Handbook" for circuit designers, FPGA developers, and electronic device developers. It introduces the importance of GND, voltage drop, and the significance of "power/GND reinforcement" in relation to DC analysis and load variations. Additionally, it includes information on "impedance disturbances and countermeasures," such as the disruption of impedance and its solutions.
