Abstract
A voltage regulator for one or more dies in a multi-stack integrated circuit includes an inductor located on a die, a voltage controller that is electrically coupled to the inductor and is also located on the die, and a capacitor that is electrically coupled to the inductor and the voltage controller and is also located on the die. The inductor defines an interior space and the voltage controller and the capacitor are located within the interior space of the inductor. The inductor can be a lateral inductor or a through layer via inductor. The multi-stack integrated circuit may have multiple dies. A voltage controller may be electrically coupled to each of the dies, although it may be located on only one of the dies. Alternatively, separate voltage controllers may be electrically coupled to each of the multiple dies and may be located on each of the respective dies.
