Yes, in all cases the current is 30x reduction with compensation in the circuit i attached before.
But the compensation becomes worse in high temperature(higher than 110'C), because the Vgs of Pmos is reduced with temperature increasing, so the bipolar which helps copying the current works in saturation region in high temperature. But the base voltage cannot be pulled low very much, because the input pair have to work in active region and needing more margion, too.
Anyhow, there is a tolerance.
Thank you very much.
