CURVATURE COMPENSATED BANDGAP VOLTAGE REFERENCE

[gevy]

I develop high precise bandgap voltage reference.
To advise me books and articles about curvature compensated bandgap voltage reference.
If you have accomplished same projects , tell me what technique for curvature compensation you used and what parameters you achieved?

Try this one. It may help. This adds a PTAT^2 voltage to do curvature compensation

This book will help you, and its references.
