Abstract

See full text

An apparatus such as heterogeneous device includes at least a first die and a second die. The apparatus further includes a first inductive element, a second inductive element, and switch control circuitry. The switch control circuitry is disposed in the first die. The switch control circuitry controls current through the first inductive element to produce a first voltage. The first voltage powers the first die. The second inductive element is coupled to the first inductive element. The second inductive element produces a second voltage to power the second die. The first die and second die can be fabricated in accordance with different technologies and in which the first die and second die withstand different maximum voltages. A magnitude of the first voltage can be greater than a magnitude of the second voltage.
