Op amps excel at providing many useful and clever solutions to routine or complicated circuit functions. A summing circuit is a perfect example. A summing circuit is typically used in applications ...

The operational amplifier (op amp) is the fundamental building block of all types of analog circuits. There are literally thousands of different ones available from dozens of vendors, ranging from ...

Modeling on Mondays: A Comprehensive and Speedy Op-Amp SPICE Model Despite the monolithic op amp being older than SPICE simulators, comprehensive op-amp SPICE modeling left a lot to be desired—until ...

This circuit in Figure 1 produces the amplitude curve illustrated in Figure 2. 2. Wideband Response for Circuit of Figure 1. The voltage gain of the op amp stage itself is 20, but this is cut in half ...

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary advantages over conventional amplifiers are reduced part counts, increased reliability, and ...

When you see a project with a digital display these days, you’ll be forgiven for assuming that there’s some kind of microcontroller behind the scenes. And while that’s often the easiest way to get a ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

Engineers are frequently faced with the challenge of developing applications to meet a wide range of requirements. Usually, these requirements are difficult to fulfil simultaneously. One example is ...

You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original op amp. I was ...
