Abstract
A scaled voltage supply to supply voltage biases to circuits in voltage zones. The scaled voltage supply includes a master voltage corresponding to a voltage drop across a master-upper rail having a voltage Vand a master-lower rail having a voltage V=0. Further, the supply includes a voltage-divider network dividing the master voltage Vinto intermediate voltages αV, βV, etc., wherein α and β are predetermined constants. These intermediate voltages scale with the master voltage and are supplied to the voltage zones using non-invasive soft rails. In one implementation the soft rails use voltage mirrors to supply the intermediate voltages to the circuits within voltage zones.
