  • Create A 250-MHz Bandwidth Digital Potentiometer For Video Level Control

    By Georgi Georgiev, July 10, 2008

    A circuit used to control the level of a video signal should have a 3-dB cutoff frequency of greater than 5 MHz for a television application or 100 MHz for a monitor application. CMOS-based digital potentiometers typically cannot be u

  • Get Powerless Indication Of Video Signals For Less Than $1

    By Pascal Frehner, May 25, 2006

    Lots of modern monitors feature an indication of incoming video signals, even if the monitors are switched off. In most cases, an LED provides this indication by fading (slowly increasing and decreasing) its light intensity. This type of indication is ve

  • "Zero-Drop," 0.5-A Voltage Regulator Costs Under $1

    By Oleg Ayranov, November 29, 2004

    Low-drop voltage regulators get wide application soon after they appear on the semiconductor market, mainly because of power savings in ac-dc supplies. Proceeding in the same direction to minimize the losses, we developed a "zero-drop" linear...
