Abstract
Reference generator embodiments are provided with low output impedances to enhance reference stability in the presence of varying loads. The generators are structured to provide these impedances in an efficient manner (i.e., with low supply currents) and also to provide both sink and source currents to better handle large transient current demands. The generators also include cascode structures that facilitate operation with low values of a supply voltage and that provide a low sensitivity to variations in this supply voltage. The embodiments are especially suited for use in signal converter systems.
