摘要:
For one disclosed embodiment, error is sensed in a voltage at an output node. One or more analog signals are generated based on the sensed error. One or more generated analog signals are converted into one or more digital signals. The voltage at the output node is controlled in response to the one or more digital signals.

A series voltage regulator circuit includes first and second voltage regulators, a first controller to control an output voltage of the first voltage regulator, and a second controller to control an output voltage of the second voltage regulator. The voltage regulators preferably include internal control loops which rapidly respond to the load variations, however the controllers operate independently from these variations. By isolating the controllers from the load, the controllers are able to maintain the output of the regulators at a constant value. In one embodiment, the voltage regulators are connected in a push-pull configuration for driving the load.

A device comprises an active-pull-up stage and an active-pull-down stage. The device receives at least one reference voltage and provides an regulated output voltage to at least one load. The active-pull-up and active-pull-down stages are adapted to source or sink a current delivered to or received from the at least one load to regulate the output voltage provided to the at least one load. Other embodiments and methods are also claimed and described.

Methods of manufacture of integrated circuit inductors having slotted magnetic material will be described. The methods may employ electro- or electroless plating techniques to form a layer or layers of magnetic material within the slotted magnetic material structure, and in particular those magnetic material layers adjacent to insulator layers.

An integrated circuit (IC) package is disclosed. The IC package includes a first die; and a second die bonded to the CPU die in a three dimensional packaging layout.
摘要:
An embodiment is a magnetic via. More specifically, an embodiment is a magnetic via that increases the inductance of, for example, an integrated inductor or transformer while mitigating eddy currents therein that may limit the operation of the inductor or transformer at high frequency.

A method and apparatus for multi-phase transformers are described. In one embodiment, a coupled inductor topology for the multi-phase transformers comprising N primary inductors. In one embodiment, each primary inductor is coupled to one of N input nodes and a common output node. The transformer further includes N−1 secondary inductors coupled in series between one input node and the common output node. In one embodiment, the N−1 secondary inductors are arranged to couple energy from N−1 of the primary inductors to provide a common node voltage as an average of N input node voltages, wherein N is an integer greater than two. Other embodiments are described and claimed.
