Cover Story

  • EDN hands-on project: Accelerate your performance

    This two-part series explores the increasing options for hardware acceleration and how designers without hardware backgrounds can benefit from evolving development tools.

Design Features

  • Getting the most from Class D multichannel audio amplifiers

    Top-rate performance means understanding clocking, power supplies, and transistor-switching characteristics.
  • Proper pc-board layout improves dynamic range

    Modern IC amplifiers, with ultralow harmonic distortion, can improve dynamic range in a variety of applications. However, placing these amplifiers on a pc board requires special attention, because poor pc-board layout can degrade distortion by as much as 20 dB.
  • Power and wireless options extend Ethernet's reach

    Ethernet's power-delivery and wireless abilities offer new application potential that hugely extends the reach of the IEEE's 802.x series of standards.
