Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

Operational amplifiers (op amps) are almost the perfect amplifier. As long as you keep a few important details in mind, their imperfections will seem invisible. Figure 1. This simple non-inverting op ...

Operational amplifiers (op-amps) are almost the perfect amplifiers. As long as you keep a few important details in mind, they will seem perfect. In part 1, I gave a simplified explanation of how an op ...

A persistent issue with Op-Amps is thermal drift — a phenomenon where the amplifier’s input offset voltage varies over time and with temperature fluctuation. Operational Amplifiers (Op-Amps) are ...

In the world of audiophilia there are arguments that rage over the relative merits of particular components. Sometimes this can reach silly levels as in the high-end ALPS pot we once saw chosen as a ...

Abstract: This paper describes SPICE-compatible macromodels to model the nonlinear behavior of operational amplifiers (Op Amp) and current feedback operational amplifiers (CFOA). The proposed ...

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 ...

Abstract: This paper presents a high-speed CMOS OP Amp with a dynamic switching bias circuit capable of processing video signals of over 2 MHz with decreased dissipated power. The OP Amp, capable of ...

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 ...

A current-mode operational amplifier (op amp) is configured quite differently from the garden variety op amps we usually use. That configuration and its algebraic circuit analysis will be covered here ...
