Hi,
I've designed a simple two stage op amp, and everything works up to ~100 deg celcius. Once I reach high temperatures like around 100 degree celcius, my pmos active load of the diff amp and the pmos of the 2nd stage amp both go into triode.
Can someone please advise why this may be and anything I can do to fix it?
Thank you!
