  1. Nick Ierfino Electronic Design In many situations, designers must control the phase of an output signal in order to make certain circuits work properly. At low frequencies, an op amp can be used to vary the phase. But as the frequency gets into the ...

  2. Christophe Basso EDN Although an SMPS (switch-mode power supply) can protect itself against permanent short circuits, it sometimes has problems when dealing with transient overloads. Transient overloads are not short circuits but can push the power ...

  3. Steve Hageman EDN Since the late 1970s, designers have successfully improved the effective resolution and spurious performance of A/D converters by adding dither uncorrelated noise to a converter's input and then using DSP techniques to average ...

  4. Tom Gay EDN Most current microcontrollers offer I/O ports that can change their functions during program execution. As outputs, the circuits can sink and source reasonably large amounts of current. This Design Idea shows three alternative methods ...

  1. Scot Lester EDN Targeting use in portable-system applications that require raising a battery's voltage to a higher level, IC boost regulators often include output transistors that can drive storage inductors. However, most boost regulators' ...

  2. Supply Maxim MAX6418
    Eric Schlaepfer, Maxim Integrated Products EDN Microprocessors, microcontrollers, and SOCs (systems on chips) often need a reset pulse to initialize properly. Many of these devices also use separate I/O- and core-voltage supplies. When you use ...

  3. Andreas Grün EDN Often, you need to transmit a couple of bits or bytes of data to a microcontroller without a direct cable connection. One simple way to achieve this goal is to use a widely available IR receiver, such as a TSOP17xx or similar ...

  4. Supply Maxim MAX756
    Navid Mostafavi EDN The step-up switching-converter circuit in Figure 1 presents a familiar problem: If you shut down boost converter IC 1 by pulling its /SHDN input low, external inductor L 1 and forward-biased Schottky diode D 1 allow the load to ...

  5. Wayne Sward EDN The circuit in Figure 1 efficiently monitors common digital-audio signals. One format for such signals is the Audio Engineering Society (AES) 44.1- or 48-kHz standard. Typically, the data consists of a serial data stream with a data ...

  6. Digital Maxim MAX1658 MAX5400 MAX7301
    Steve Hageman EDN To test products in my R D lab, I build many universal data-acquisition systems that connect to a PC or another controller through RS-232 links or LANs. These small systems typically include multiple ADC, DAC, and digital-I/O ...
