  1. Class D audio amplifiers provide a dual benefit for battery-powered portable devices (Figure 1). They enhance battery life, and they produce much less power dissipation than do their linear cousins. Those features make Class D amplifiers ideal ...

  2. The simple peak detector in Figure 1 is the result of a need for a single-5V-supply, level/clipping indicator for a multimedia-PC sound system. The design is unique in that it detects both stereo channels on a single peak-hold capacitor. All the ...

  1. Philip Karantzalis EDN In low-noise analog circuits, a high-gain amplifier serves at the input to increase the SNR. The input signal level determines the input-stage gain; low-level signals require the highest gain. It is also standard practice in ...

    Guy Hoover, Analog Devices Electronic Design A high-resolution SAR ADC often needs a higher-order antialiasing filter, such as the third-order version provided by this low-noise, low-power design. For many analog-to-digital converter (ADC) ...

  3. Thomas Mosteller, Christopher Jarboe Analog Dialogue Question: Can I produce a compact, ultralow noise, phantom power supply (48 V) from a 5 V, 12 V, or 24 V input? Answer: You can, using a simple boost converter, a filter circuit to reduce EMI, ...

  4. Henno Normet Electronic Design The amplifier within a standard AV receiver can become a fully adjustable, three-phase power supply by adding a general-purpose op amp, a few passive components, and some standard transformers. If you need an ...

  5. Derek Bowers Electronic Design Early radio receivers and record players nearly always had a knob marked “tone,” which was usually a crude low-pass filter with some form of severity adjustment. At best, these controls could partially ...

  6. Dave Conrad EDN There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total solution cost; such as boosting ...

  7. José M Miguel EDN Testing audio-noise-reduction circuits, PLLs (phase-locked loops), and audio-frequency filters may require a noisy sine wave, one that is summed with white noise. Using a typical computer sound card, free software, and an ...

  8. John Guy, Maxim Integrated EDN The increasing acceptance of Class D amplifiers has helped them gain market share from their linear Class AB brethren. That acceptance is no surprise; the advantages of Class D amplifiers are legion, but such ...
