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 res… ...

The op amp's inputs are made up of an inverting input (V in-) and a non-inverting input (V in+). In the ideal case, the op amp amplifies the difference in voltage between the two inputs.

Obviously, if you put in 12V it won’t be able to produce 24V on a 15V supply, so be reasonable. Non-inverting amplifier example ...

Part 1 of a two part article. Click here for Part 2 Originally, operational amplifiers (op amps) were not thought of as candidates for RF design, but the advent of newer, faster devices has now made ...

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 ...

NA1, NA2, NA3, NA4, and NA5 are non-inverting buffer amplifiers. IB1, IB2, IB3, IB4, and IB5 are the corresponding inverting buffer amplifiers.
