Op-amps, or operational amplifiers, are versatile and widely used components in electronic circuit design. They can perform various functions, such as amplification, filtering, buffering, and ...

Efficiently Design An Op-Amp Summer Circuit To design a balanced circuit, select R F (such as 100 kΩ), and calculate R I for each input by dividing R F by the magnitude of the gain.

In this article, you will learn how to analyze op-amp behavior in analog circuits using some basic concepts and techniques. Selected by the community from 16 contributions.

If you have read my first blog, you may have noticed that I really like op amps. My primary expertise lies in designing them, but I’m also intrigued by clever op-amp application circuits. To promote ...

The output power is 62.5 mW and, of course, varies with the load resistor. Notice how this circuit fits the second rule, though.

This feature is realized with CMOS circuits. For instance, if an op amp uses ±5-V supplies, the output can swing over the full range from – 5 V to + 5 V or 10 V.

Looking at the circuit diagram it follows the classic op-amp with a long-tailed pair of NPN transistors driving a PNP gain stage and finally a complimentary emitter follower as an output buffer.

This reduces the output voltage of the op-amp, subsequently decreasing the laser intensity. The opposite behavior is seen with a drop in laser output power. This circuit was built on a breadboard ...

As mentioned, the gain is independent of the supply voltage. For more about op-amps, see Op-Amps Are Used Widely in Broadcast Circuits Note: The deadline to sign up for the next SBE certificate exams ...

Figure 1: The circuit can test single, dual and quad op-amps. “The results of the test are displayed using low current LEDs. If the output of the op-amp is high, the red LED will light; if the output ...

Fig. 2: Unity-Gain Follower (Non-Inverting) With the invention of the transistor in 1947 (see our related Milestone article “The Transistor Portable Radio”), a parallel development program of tube and ...
