In my previous article on common op-amp circuits, I mentioned that operational amplifiers were used for analog computing, where analog circuits simulated the behavior of complex systems. That article ...

We took a look at op amp integrators in the previous article, Op amps do integration, so it makes sense to round out the picture by covering differentiator circuits. Of course, differentiation is the ...

To have stability and to reduce noise, a resistor R 1 is placed in series with C 1 and a capacitor C f is placed in parallel with R f in a practical differentiator circuit. The output of an integrator ...

Engineers often encounter difficulty when attempting to accurately rectify low-amplitude AC signals using standard diode-based circuits. The primary issue arises from the diode’s forward voltage drop, ...

This book is designed for students who are taking their first course in analog electronics in either a two-year or four-year program. The prerequisites are a DC-AC course; a basic knowledge of algebra ...

Bob Pease got an e-mail in 2006 from an engineer who was having trouble with an integrator circuit. Amplifiers are often called op amps because they were originally used as operational amplifiers.

In my previous DAC7821 article, "Hands-On with Analog Circuits & AI, Part 3: Real-World Implementations of Digitally Controlled Amplification," I built and tested a programmable-gain single-stage ...
