Abstract
Techniques described herein are related to spread amplifier having a differential amplifier spread (DAS) configured to receive a pair of input signals and to provide a plurality of graded outputs each having different output levels. The spread amplifier further includes a final driver stage having a plurality of final drivers, wherein each of the final drivers is configured to receive a respective one of the plurality of graded outputs. The spread amplifier may be used for the regulation of various voltages such as VDQS and VARY.
