  1. Jean-Bernard Guiot EDN Computers find universal use in industrial-control systems. During power- and start-up sequences (booting), the outputs of such control systems may yield uncontrolled pulses before the software defines the correct status. If ...
  2. Erjon Qirko and Kris Lokere, Linear Technology Design Note 1039 Introduction The LT6018 is an ultralow noise (1.2 nV/√Hz at 1 kHz) operational amplifier with ultralow distortion ( 115 dB at 1 kHz). It has a gain bandwidth product of 15 MHz, ...

  3. Reza Moghimi, Analog Devices EDN This Design Idea offers a new instrumentation-amplifier topology that improves ac CMR (common-mode rejection). Because it uses discrete amplifiers, you can customize it for the lowest power, price, noise, and supply ...
  4. Arturo Rivera EDN This Design Idea avoids the RC charging waveshape of a standard relaxation oscillator, replacing it with a linear rise/fall triangle wave. Positive feedback is used to increase the charging rate over each half-cycle and straighten ...
  5. Fons Janssen, Maxim Integrated EDN Introduction High-capacity, multilayer ceramic capacitors (MLCC) have a property often not well understood by electronic designers: the capacitance of these devices varies with applied DC voltage. This phenomenon ...

  6. Ron Mancini, Texas Instruments EDN The transfer gain of optical sensors spans a 16-to-1 ratio because of variations in the LED, phototransistor, ambient temperature, and optical path. The wide transfer-gain variation complicates output-resistor ...
  7. Royce Higashi and Tony Doy, Maxim Integrated Products EDN Low-profile piezoelectric speakers can provide quality sound for portable electronic devices, but they require voltage swings greater than 8 V p-p across the speaker element. Yet, most ...

  8. Jean-Bernard Guiot EDN Figure 1a shows a latching circuit based on an optocoupler, IC 1 . If the off switch remains closed, pressing the on switch powers the LED in the optocoupler. Thus, the transistor in IC 1 turns on. You can now release the on ...
  9. 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 ...
  10. J Jayapandian EDN Numerous programmable-gain amplifiers are available, but a simple solution provides the option of using 256 gain steps with an 8-bit DAC and higher steps with higher bit DACs (Figure 1). According to the inverting-amplifier ...
