- Jim Tonne Electronic Design With a handful of low-leakage passive components and two high-impedance op amps, you can build a sine/square-wave generator with output period of a minute and more. The circuit of Figure 1 generates sinusoids down to ...02-04-2018
- Nick Ierfino Electronic Design It’s not always easy to design a ramp generator whose ramping frequency can be changed without manipulation of capacitors or inductors. Many ramp circuit designs are available, but they may not be flexible when ...19-03-2018
- 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 ...08-02-2018
- 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 ...08-02-2018
- 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 ...09-11-2017
- 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 ...Circuits »31-10-2017
- 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 ...02-05-2017
- 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 ...02-03-2017
- 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 ...Circuits » ·26-02-2017
- 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 ...19-01-2017
