  2. Jesus Rosales, Linear Technology Design Note 545 Introduction Industrial, telecom, medical and automotive applications use a wide variety of regulated voltages to operate effectively, including high voltage and negative rails. When the designer is ...
  3. Peter Baxter EDN This Design Idea shows how to use a 63¢ (Q=1) microprocessor reset voltage detector IC in a relay coil drive circuit to greatly reduce the coil’s hold-in current. When asked to estimate the coil current of a small Omron ...
  4. Louis Vlemincq Electronic Design The use of a copper winding as a temperature sensor is not new. The traditional technique is to disconnect the ac power and the load and to quickly make the measurement using an ohmmeter. But the circuit presented ...
  5. Michael Dunn EDN Most electronics today requires multiple supply voltages four or more rails is not uncommon. But if you're using multiple, unsynchronized DC-DC converters, you've not only got a sub-optimal design, you're asking for ...
  6. Domenico Di Mario, Italy This circuit was specifically designed to recharge alkaline cells. The unusual connection of the transistor in each charging unit will cause it to oscillate, on and off, thus ...
  7. Glen Chenier EDN You can assemble a pulse-generation circuit from a simple Schmitt-input AND gate plus a resistor-capacitor timing network. However, if you need a logic function that's not a standard catalog item, you need a Schmitt-input gate ...

  8. Alfredo Saab EDN Analog applications, such as testing, calibration, and general system operation, often require a sine waveform of accurate amplitude and frequency, with low THD (total harmonic distortion). Some applications demand that the ...

  9. I’ve just finished a little Arduino project. It’s a shield for the Arduino Uno that lets you measure inductance. This is a functionality that I found missing in just about any digital multi meter. Yes, there are ...
  10. Sam Young, Afshin Odabaee Linear Technology Design Note 546 Introduction The top side of a typical system board, such as a PCIe card, is densely populated with FPGAs/ASICs/ microprocessors, transceivers, connectors, memory ICs and DC/DC regulators, ...
