  2. Gheorghe Plasoianu EDN Bench electronic loads are usually rated for voltages less than 100 V, which make it difficult to test high-voltage power supplies. This Design Idea offers an alternative: an inexpensive electronic load rated for 500 V or ...
  3. Jon Munson, Linear Technology Design Note 513 Introduction Accurately measuring voltages requires minimizing the impact of the instrument connection to the tested circuit. Typical digital voltmeters (DVMs) use 10 M resistor networks to keep loading ...

  5. 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 ...
  6. 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 ...
  7. Francesc Casanellas EDN Figure 1 illustrates a digitally programmable precision resistance that can serve as a microprocessor-driven power-supply load in custom-designed ATE (automatic-test equipment). An 8-bit current-output DAC, IC 1 , a DAC08 , ...
  8. Chee Hua How, TDK Malaysia Electronic Design Bench evaluation of transistors’ h FE may be needed during development of a system to ensure reliability of production systems. This circuit permits such testing using pulsed current and the ...
  9. Karen Hunsberger Electronic Design This frequency upconverter circuit is a simple alternative to doing period measurement or accepting long latency when measuring very low frequencies, on the order of one to 100 Hz. Engineers occasionally need to ...

  10. A Hunt EDN When I was recently debugging a design, I discovered that a short circuit existed from a ground plane to a power plane. I did not have access to a milliohmmeter or an equivalent tester for locating this type of short circuit. So, I ...
