  1. 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 ...

  2. Jianwen Shao EDN Due to their light output and long life, high-brightness LEDs are well-suited for use in flashlights. Typically, the LEDs are driven with a constant current. So when the battery voltage drops, the flashlight just stops working. In ...

  3. Abel Raynus EDN In analog design, you might need to create an amplifier with nonlinear dynamic characteristics for example, logarithmic, exponential, or square-law. Usually, such amplifiers are complicated. However, the project often does not ...

  4. Tommaso Angelino Electronic Design A microcontroller's internal ADC was inadequate to measure its own supply rail, so a circuit using standard discrete components was devised to do this with just one pin of the IC. This circuit solved a problem ...

  1. Spehro Pefhany EDN Occasionally, you have access to a transformer for powering a dc circuit, but its output voltage is much higher than that required for the dc voltage. The full-wave-rectified and filtered output of an ac input voltage V X , is V ...

    Fabio Cacciotto, STMicroelectronics EDN Modern appliances offer a range of features that rely heavily on microcontrollers and auxiliary circuits. Although conventional iron-core transformers can provide ac line-isolated, low-voltage power for a ...

  3. Steve Woodward EDN A sensitive and reliable way to measure airflow is to take advantage of the predictable relationship between heat dissipation and air speed. The principle of thermal anemometry relies on King's Law, which dictates that the ...

  4. JB Castro-Miguens, C Castro-Miguens EDN Protect circuits from high current until a capacitor charges A high-power offline supply is nothing more than a half- or full-bridge dc/dc converter. Rectifying the ac line yields a dc voltage that feeds the ...

  5. Jim McLucas EDN A recent Design Idea described a method for designing simple, high-frequency LC oscillators with few passive components ( Reference 1 ). However, for best results, practical hardware design of a stable oscillator requires more parts ...

  6. Alex Rysin Electronic Design This idea analyzes the reason that a capacitively coupled load may result in a clipped negative output, and shows the conditions that must be met to avoid this undesired situation. An engineer asked me for help when he ...
