  1. Jim Williams EDN Impulse-response and rise-time testing often require a fast-rise-time source with a high degree of pulse purity. These parameters are difficult to achieve simultaneously, particularly at subnanosecond speeds. The circuit in Figure ...
  2. Bob Marshall EDN In new mixed-voltage systems, it is often necessary to level-shift a control signal from a high level to a low level. An open-drain device, such as the 74LVC2G07 , easily performs this shift. However, when a bidirectional signal ...

  4. Praveen K Electronic Design In certain applications, like pH measurement based on electromagnetic field (EMF) changes in an electrochemical reaction, the change in voltage is very small and the voltage range varies with the solution's ...
  5. Al Dutcher EDN The circuit in Figure 1 allows you to light any type of LED from a single cell whose voltage ranges from 1 to 1.5 V. This range accommodates alkaline, carbon-zinc, NiCd, or NiMH single cells. The circuit's principal application ...
  6. Jim Grant EDN A white LED delivers a wide color spectrum and better visibility than do monochromatic LEDs. However, a white LED presents a higher forward-voltage drop than do its colorful counterparts and thus poses problems for operation from a ...
  7. Stephen Woodward EDN Unusual design constraints sometimes reveal the unfriendly side of everyday components and circuits. A case in point is the design of power-supply-regulation circuitry in which the primary power source has an absolute ...
  8. Tim Regan Electronic Design Environmental concerns are spurring the development of clean transportation alternatives. Most popular are full electric and hybrid electric motor vehicles, which use stacks of lithium-ion battery cells as the electric ...
  9. Earlier portal Radiolocman has published a description of two devices for for automatic lighting of the working area in the kitchen: Arduino version and NodeMCU version . The latter, despite several disadvantages, which I will report at the end of ...
