Mathematical formulation of restrictions for the design of low voltage bandgap references

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2012
Nowadays the qualities more looked for in the design of bandgap references are the low potential of the reference and the low value of its coefficient of temperature, being these parameters more favorable in curvature corrected bandgap references.
