Abstract
This disclosure relates to embodiments that include an apparatus that may comprise a first layer including a first plurality of active devices, a second layer including a second plurality of active devices, and/or a third layer including a plurality of passive devices and disposed between the first and the second layers. An active device of the first plurality of active devices and an active device of the second plurality of active devices may influence a state of charge of a passive device of the plurality of passive devices.
Claims29
An apparatus comprising:
- a first layer including a first plurality of active devices;
- a second layer including a second plurality of active devices;
- and
- a third layer including a plurality of passive devices and disposed between the first and the second layers,
- wherein an active device of the first plurality of active devices and an active device of the second plurality of active devices influence a state of charge of a passive device of the plurality of passive devices.
An integrated circuit comprising:
- a first layer including at least two passive devices;
- a second layer including at least four active devices to influence a state of charge of a passive device of the at least two passive devices;
- and
- an interconnect layer disposed between the first and the second layer to electrically connect the two passive devices and the four active devices to form a DC-to-DC power converter.
A method of forming an apparatus, the method comprising:
- forming a first layer including a first plurality of active devices;
- forming a second layer including a second plurality of active devices;
- and
- forming a third layer including a plurality of passive devices and disposed between the first and the second layers,
- wherein an active device of the first plurality of active devices and an active device of the second plurality of active devices influence a state of charge of a passive device of the plurality of passive devices.
A method of forming an integrated circuit, the method comprising:
- forming a first layer including at least two passive devices;
- forming a second layer including at least four active devices to influence a state of charge of a passive device of the at least two passive devices;
- and
- forming an interconnect layer disposed between the first and the second layer to electrically connect the two passive devices and the four active devices.
