In the fantasy world of schematic diagrams, wires have no resistance and square waves have infinitely sharp rise times. The real world, of course, is much crueler. There are many things you can use to ...

Figure 1 Use a portion of a programmable-logic device or gate array to implement a Schmitt-trigger buffer (a) by adding either two (b) or four external resistors (c). Thanks to its internal hysteresis ...

Back to analog, let us start some Schmitt trigger experiments with jellybean bipolar junction transistors… This post explores the classic emitter-coupled Schmitt Trigger circuit. A Schmitt trigger is ...

The classic Schmitt-trigger-based RC oscillator is "hacked" and analyzed using the simulation software QSPICE.

In this Design Idea, we look at how electromechanical relays display hysteresis behavior that is surprisingly similar to the solid-state Schmitt trigger circuits, and how they can be used for many ...

We have already given many posts on Op-Amp circuits. But the list of applications of Op-Amp will be keep on going. The best Op-Amp circuit which is used to convert sine waveform into rectangular ...

The CD4093B consists of four Schmitt-trigger circuits. Each circuit functions as a 2-input NAND gate with Schmitt-trigger action on both inputs. The gate switches at different points for positive and ...

In 1938, the Journal of Scientific Instruments published details of a comparator circuit that converted a slowly varying input signal into an abrupt change in output voltage. Based on cross-coupled ...

Amplifiers with positive feedback are the bases of signal-grade pulse-forming circuits. This setup ensures a triggerlike operation in which the input signal crosses the input-threshold level; in most ...

“We need a circuit that generates a UV LED light pulse for a couple of seconds over about a 30-second period,” said the manufacturer of a portable aftermarket product with a florescence element. The ...
