    Sponsored by: NATIONAL SEMICONDUCTOR

    By Gene Heftman, March 29, 2004

    Signal conditioning often consists of converting an analog signal from a sensor in the physical world into a digital signal that can be used for data collection, controlling a process, performing calculations, producing display readouts, and other...

  • Controller ICs Energize Power-Supply Design

    By Gene Heftman, March 01, 2004

    Build or buy? That question tops the list when systems designers decide how to supply dc power at the growing number of voltage and current levels present in virtually every type of electronic system. As supply voltage levels drop and currents rise,...

  • High-Voltage DC-DC Conversion
    Sponsored by: NATIONAL SEMICONDUCTOR

    By Gene Heftman, February 16, 2004

    The delivery of dc voltages and currents to ICs in modern communications systems is turning traditional power-supply design into a new art form, driven by the need for greater bandwidth, faster data rates, tighter security, upgradability, larger...

  • Miniature Packaging
    Sponsored by: PHILIPS SEMICONDUCTORS

    By Gene Heftman, December 18, 2003

    The packaging of electronic devices is an evolving art driven by the requirements of smaller, lighter, portable, battery-powered products, such as cell phones, PDAs, notebook computers, CD-ROM players, and so forth...

  • Op Amps
    Sponsored by: ANALOG DEVICES
