Hi, I have referred this paper for designing current reference.
But, I have not used cascode transistors (like PMOS cascode shown in the reference)
I obtained a temperature coefficient of 650 ppm /C.
The major concern is that some transistors entered linear or cutoff region at few points in the plot versus temperature.
However, the generated current ( temp co 650 ppm) ensured that transistors in the main amplifier remained in saturation
What impact will this have on the chip?
