Bandgap Reference Layout Analysis and Design
Keywords:
Bandgap, layout, supply-independence, temperature-independence, mismatch, matching.Abstract
Analog circuits incorporate voltage and current
reference extensively. Such references are dc quantities that exhibit little dependence on supply and process parameters and a well-defined dependence on the temperature. In systems such as A/D and D/A converters and so on, a reference is required to define the input and output full-scale range. In this paper, the analysis and layout design of reference generator in
CMOS technology are deal with, being focused on
well-establishing “bandgap”supply-independent
biasing technique.is studied. First, Next, temperature-independent references are described and issues
such as the effect voltage are examined. Third, bandgap reference layouts are designed and the results are given. Finally, an example of state-of-the-art bandgap references are studied.
