Comparison of Kuijk and Brokaw Voltage Reference Architectures For High Precision on-Chip References
Voltage references in the range of 2.5V are normally generated by scaling a 1.2V reference. This paper
compares two popular 1.2Vreference architectures, Kuijk and Brokaw architectures in a unified manner. The two
architectures are designed under common design conditions using AMS 0.35µm technology. The architectures are compared
in terms of reference voltage temperature drift, variation across process corners. Various sources of error in both the
architectures are also discussed in this paper. For a 2.5V high precision voltage reference, Brokaw architecture seems to be
