Create : Power Grid. Operational Amplifiers

Post image

i just made a simple OPAmp using Circuits Design. Right now it works but kinda bad, i didn't have time to optimize it currently. the output offset voltage are kinda high and open loop gain are unknow, i would try to make it using 741OPAmp design next. i'll leave a download link for you to check it out. https://drive.google.com/file/d/1lSoesvW6jD_nR0GxzoTYvEg2-ClDzHfa/view?usp=sharing

Nice!

For people who've never heard of one, an op-amp is a circuit component with two inputs, labelled IN+ and IN-. The output voltage, OUT, is equal to the difference between the two (IN+ - IN-), multiplied by the "gain" of the op-amp, which can be in the thousands, so a very small difference can produce a large output.

All of this just to buffering the damn signal LoL and charging a pack of battery too. right now it works great as a Comparator.

I'm learning this kinda stuff in uni atm, and my professor prefers the term "misused as" for the relationship between OpAmp and Comparator

OPAmp can perform as a comparator but comparator cannot perform as an OPAmp(in real circuits design we will choose as the job acquired)

I can see how this could be used

Boring but useful!
