This reduces the output voltage of the op-amp, subsequently decreasing the laser intensity. The opposite behavior is seen with a drop in laser output power. This circuit was built on a breadboard ...

We are all used to the op-amp, as a little black box from which we can derive an astonishingly useful range of circuit functions. But of course within it lurks a transistor circuit on a chip, and u… ...

The real world is analog, and the op-amp is the indispensable building block of many analog circuits. We wanted to give you analog fanatics out there a chance to shine and to encourage our digital … ...

Op amps are the basic building blocks for much of linear circuit design. You probably learned about them in college and even designed some products containing an op amp. As an electronic engineer ...

For instance, a typical rail-to-rail output op-amp can’t provide true zero voltage, it can guarantee at least several mV on its output, while a high-resolution DAC can have resolution in the of tens ...

What you’ll learn: Bob Pease and Walt Jung provide an excellent overview of the K2-W’s circuit design. Philbrick Researches’ K2-W is a very-high-gain op-amp design using only two vacuum tubes.
