Dec 19, 2022 at 20:28 comment added Kuba hasn't forgotten Monica That's the approach I'd recommend. It's cheap and performs quite well. The mosfets have enough gate-drain capacitance to stabilize the op-amp, usually. The connections to R1 should still be Kelvin of course! Nothing can work around that.
