  1. Shyam Tiwari EDN Digital oscillators often generate TTL- or CMOS-level outputs, referred to ground. Generating a symmetric bipolar output with respect to ground presents a challenge. In this design, four 1.5 V flashlight cells create 3 V voltage ...

  2. Moshe Gerstanhaber EDN The multivibrator is a common circuit that consists of an amplifier with both positive and negative feedback (Figure 1a). When the output is positive, the positive input terminal equals ½V+, and the voltage at the ...

  3. José M Miguel EDN Testing audio-noise-reduction circuits, PLLs (phase-locked loops), and audio-frequency filters may require a noisy sine wave, one that is summed with white noise. Using a typical computer sound card, free software, and an ...

  4. Ferran Bayes EDN A previous design idea is reminiscent of a similar but somewhat simpler circuit (see [1]). This circuit delivers a rectangular signal with duty cycle varying between 0 and 100% in response to an input signal varying from 0 to 5 V ...

    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 ...
