  1. Marián Štofka EDN Using a shift register with parallel output is a common way to design a pulse generator with N inputs and pulsed outputs having a width of T/N. To keep the output pulses consecutive, you can use feedback from the ...

  2. Arturo Rivera EDN This Design Idea avoids the RC charging waveshape of a standard relaxation oscillator, replacing it with a linear rise/fall triangle wave. Positive feedback is used to increase the charging rate over each half-cycle and straighten ...
  3. Glen Brisebois EDN Ideal triangle waves involve infinite d 2 V/dt 2 , so high-fidelity triangle waves entail very high bandwidths. Micropower circuits have fairly low bandwidth, so generating good triangle waves with such circuitry becomes ...
  4. Guus Colman EDN In many applications, the frequency-conversion steps comprise a buffer, preferably with some extra voltage gain; a mixer; and some filtering. Instead of including an amplifier in front of the mixer, you can easily integrate the ...
  5. 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 ...

  6. Al Dutcher EDN This Design Idea provides a simple, inexpensive, portable circuit as an alternative to a microcontroller to provide a wide-range source of low-distortion sine waves for audio-circuit design and debugging. Although sine waves from DDS ...
  7. Jim McLucas EDN A recent Design Idea described a method for designing simple, high-frequency LC oscillators with few passive components ( Reference 1 ). However, for best results, practical hardware design of a stable oscillator requires more parts ...

  8. Louis Vlemincq EDN This Design Idea applies a novel topology to an oscillator. It uses a series-connected LC (inductive-capacitive) tank circuit to give the circuit a higher tuning range than circuits that use a parallel-LC connection. The ...
  9. By Chau Tran, Analog Devices EDN Europe In many audio, automotive and instrumentation applications, there are requirements for a low cost but highly stable and accurate square wave generator with a respectable level of output current drive. As we ...
  10. Einar Abell EDN This Design Idea demonstrates a simple way to turn a step input into a ramp of nearly constant slew rate. The basic circuit uses a single op-amp; a circuit built on an integrator will typically require three. Figure 1 shows the ...
