Although I used op amps in many feedback loops over the years, the subject of transconductance op amps versus voltage feedback op amps has always intrigued me. Therefore, I thought it would be a good ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

Electrical engineers probably remember they can switch currents faster than voltages, which is why some designers prefer current-output digital-to-analog converters (DAC) over their voltage-output ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

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

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 ...
