Abstract
This article presents a methodology to design a
circuit to compensate for process skew by exploiting an inherent
dimension-dependent effect of process skew on change in the
threshold voltage. We design a voltage reference circuit with
a hybrid architecture of bandgap reference (BGR) and CMOS
reference, which generates a nominal voltage level of (bandgap
- threshold). By compensating the process skew of the threshold
term with the proposed dimension-induced effect as well as
the temperature depen
