  1. Marian Stofka EDN A capacitor that you charge through a resistor operates at 50% efficiency; hence, many engineers avoid using switched-capacitor dc/dc converters. That efficiency figure holds true only for capacitors with no initial voltage, ...

  2. Stephen Woodward EDN Despite the ever-growing choices among single-supply “Rail-to-Rail” op-amps, it will always remain true that the only way to design an output stage active all the way down to zero volts is for the design to include ...

  3. Ron Mancini EDN Converting periodic waveforms to square waves is an integral part of extracting a clock signal from data, creating waveform generators, and making timing-pulse generators. Any square-wave-conversion circuit is more valuable when the ...

  4. Chuck Wojslaw EDN The potentiometer portion of a mixed-signal, digitally programmable potentiometer adds variability to an analog circuit, and its digital controls provide programmability. You can use a digital potentiometer in two ways in an ...
  5. John Ambrose EDN Tracking notch filters find use in harmonic-distortion analyzers; they also can remove heterodyne noise from ham-radio systems. A conventional tracking switched-capacitor notch filter relies on a bandpass filter, a ...
  6. James Zannis EDN Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply voltage, thus protecting it ...
  7. Part 1 Understanding Raspberry Pi Inputs Push Button Switch Input The connections on the Raspberry Pi can be converted into inputs under software control. The example here is about the simplest; a push button switch is wired up to the 40-pin ...
  8. element14 Introduction The Raspberry Pi is a computer, and from a connections point of view it doesn’t look much different to a normal desktop computer. It has USB ports for connecting a keyboard and mouse, and a video output port for ...
  9. Luca Bruno EDN You can use the circuit in Figure 1 to obtain a low regulated voltage, such as 5 V dc, from a higher voltage, rectified, sinusoidal voltage source without resorting to an electrically noisy dc/dc converter or wasting watts in a ...
