Abstract
A voltage reference circuit maintains two nodes at constant voltages with respect to a reference by means of a tapped divider chain in parallel with a floating voltage reference circuit, both of which feed into the output node of a single differential amplifier. The reference circuit maintains a constant voltage across the divider chain and the amplifier floats the divider up or down to maintain a node in the chain at the reference voltage.
