ABSTRACT:
A method of designing stacked circuits for an integrated circuit is described. In this method, a plurality of devices that are stackable may be determined. Some of those devices, i.e. a subset of stackable devices, may be formed in a deep n-well, thereby allowing that subset of stackable devices to receive an increased supply voltage. The remainder of the stackable devices may be formed in a standard n-well, thereby allowing such devices to receive a standard supply voltage. In one embodiment, the standard supply voltage may be VDD and the increased supply voltage may be 2×VDD. This method may be advantageously used in both the design of stacked circuits for and the implementation of stacked circuits in an integrated circuit.
