Low Impedance Design in Power Circuits

February 01, 2024 by Murata
Topics Covered
  • Need for low-impedance design
  • Methods to reduce power impedance
  • Characteristics and structure of low-ESL capacitors

White Paper Overview

Smartphones and HPC are now designed for low impedance as they require low power voltage and larger power current. This trend is likely to continue for other devices, which makes low-impedance design more important.This document describes the key points for achieving lower impedance using PDN design, decoupling capacitor types and layout, and substrate design.
