Did you ever wonder how to calculate the stability of an op amp circuit? Put the wrong compensation network into the feedback loop, and you’re got an attenuator or, worse, an oscillator. It’s not ...

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 ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

Surprise, surprise. The bandwidth of an amplifier in a gain of +1 V/V is not the same as the bandwidth of the same amplifier in a gain of –1 V/V. After more than five years of working every day with ...

Having written a little about quadature decoder chips, I have had a look around for circuits that do a similar job – sadly, I cannot recall the circuit of the one built years ago for a college ...
