I need a stable 10 uA source for a regulation circuit. I’ve played with self biased JFET current source but concerned about stability over a range of temperature. I don’t mind calibrating for manufacturing variations so mostly concerned about temperature stability. It will likely be used in stable environments and +/- 10 % over 20-40C should be ok. Is it possible to run thermal analysis in LTSpice?
