  1. Jim Williams, Linear Technology EDN If you need to produce extremely fast pulses in response to an input and trigger, such as for sampling applications, the predictably programmable short-time-interval generator has broad uses. The circuit of ...

  2. 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 ...

  3. Michael Fisch EDN In 1940, William Hewlett and David Packard launched a product from a garage. The product was a Wien-bridge oscillator. It consisted of a single-pole highpass filter in series with a single-pole lowpass filter. To keep the gain ...

  4. Louis Vlemincq EDN Many power applications ranging from luminescent and fluorescent lighting to telephone-ringing voltage generators require a more or less sinusoidal-drive voltage. These applications typically require a waveform of only moderate ...

  5. Mitchell Lee LT Journal of Analog Innovation A source of fast pulse edges, simulating a step function, is often useful in making lab measurements of one kind or another. For example, it is possible to evaluate the rise time of RG-58/U or other ...

  6. 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 ...

  7. 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 ...

  8. 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 ...

  9. 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 ...

  10. 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 ...
