Abstract: A device for providing electrostatic discharge (ESD) protection includes circuitry configured to detect an occurrence of an ESD event at one or more voltage rails. An ESD clamp is activated via a clamp triggering path to provide a discharge path for an ESD current. A gate voltage of the ESD clamp is maintained greater than a predetermined threshold via a holding path in parallel with the clamp triggering path.

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 Vdd and a master-lower rail having a voltage Vss=0. Further, the supply includes a voltage-divider network dividing the master voltage Vdd into intermediate voltages αVdd, βVdd, 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.
