I needed a low power, relatively precise electronic load for some small battery testing I am doing, so I thought it would be good practice to design one.
Because this is just a one off, I wanted to keep things simple.
I have attached the design I came up with. I simmed it and everything seemed to be fine.
Problem is, now that I have made it on a 3M breadboard, It oscillates like crazy at about 400Khz
besides the oscillation it does actually work... I get the right average current. I'd just rather have it without the crazy oscillation.
I have decoupled the LMC6482 opamp well.
Where do I start to calculate a way to kill the oscillation?
