  1. Martin Rowe EDN When converting a negative-output power supply to one with less-negative output, you must ensure that variations in input voltage don’t affect the output voltage. All such supplies include an internal reference voltage that ...

  2. Catherine Chang, Linear Technology Design Note 1045 Introduction Precision high side measurement of microamp currents requires a small value sense resistor and a low offset voltage, ultralow-power amplifier. The LTC2063 zero-drift amplifier has a ...
  3. Tommy Tyler Electronic Design This circuit uses electromechanical relays to retain its state indefinitely, even when power is off. It consumes no power except when triggered from one state to the other. Many varieties of ON/OFF control circuits use ...

  4. Philip Simpson, Maxim Integrated Application Note 1186 When a processor-controlled device must be guaranteed to operate, designers often choose to reset the processor periodically rather than rely on a watchdog circuit. In low-power systems the ...

  5. 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 ...
  6. James Mahoney EDN The circuit in Figure 1 converts pulse information to a clean dc voltage by the end of a single incoming pulse. In another technique, an RC filter can convert a PWM signal to an averaged dc voltage, but this method is slow in ...
  7. Ajoy Raman EDN This Design Idea presents a minimal-parts-count, wide-range voltage doubler using the inherent voltage-doubling characteristics of a one-transformer push-pull dc/dc converter. The implementation uses a high-voltage Darlington-array ...

  8. Wayne Ryder Electronic Design The prescaler described here connects to the front end of a 100-MHz frequency counter to extend its coverage range to 10 GHz. The circuit is a far less expensive way to measure frequencies above 100 MHz than buying a ...

  9. Gheorghe Plasoianu EDN Designing a high-voltage regulator can pose difficulties associated with component stress, reliability, and costs. This Design Idea offers a solution: a simple unregulated high-voltage supply in series with a low-voltage ...
  10. Marián Štofka EDN Pulse generators often need voltage comparators with accurately defined hysteresis, and such comparators need bipolar voltage references. Most voltage-reference-cell ICs are referenced to their low-side supply rail. ...
