Current feedback amplifiers are one of the oldest amplifier topologies around. I remember the days when Comlinear ruled the market in the 80s with their high speed offerings. Analog Devices, ...

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 ...

With both current and voltage feedback operational amplifiers (op amps) available to the system designer, how do you select which device to use? This two-part article discusses applications most ...

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 ...

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 ...
