Description

ABSTRACT:
An integrated circuit having both logic transistors and at least one power switching transistor formed on the same substrate is described, wherein both sets of transistors are powered by current received from the substrate, the power transistor being powered by current flowing directly from the substrate, and the logic transistors being powered by current flowing through a metal layer making electrical contact to the substrate.
