Filed:

Oct 27, 2000

Appl. No.:

09/703988

Inventors:

Jason P. Jacobs - San Francisco CA

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H03K 312

US Classification:

327217, 327219, 327215, 327225, 327218

Abstract:

A multiple input set/reset circuit is described that includes cross-coupled inverters connected between set and reset nodes. The set/reset circuit also includes at least one set input circuit coupled to the set node configured to receive a set signal and to drive the set node to a first logic state in response to the set signal asserted, and at least one reset input circuit coupled to the reset node configured to receive a reset signal and drive the reset node to the first logic state in response to the reset signal asserted. Incorporated into the set/reset circuit are a first switching circuit to change the logic state of one of the nodes to a second logic state when the other node changes the logic state to the first logic state, and a second switching circuit to disable the first switching circuit after the first and second nodes have completed a logical state change in response to a set or reset signal asserted.

Abstract:

An induction device has an elongated core made of two or more uniform ferromagnetic spaced-apart toroids. A first winding around the core creates an inductor. When the induction device includes a second winding, a transformer is created. The transformer acts as a powercord transformer when the exposed ends of one winding are available at one end of the elongated core for connection to a source of alternating current and the exposed ends of the other winding are available at the other end of the core for connection to a load. An inductor with a single-turn winding can be constructed by first forming the core by stacking two or more ferromagnetic toroids end-to-end and spaced apart, then threading two wires through the core center and placing two wires outside the core and connecting the ends of the wires to create the winding. A transformer can be constructed by first following the steps to create an inductor. A second winding is then created in a similar manner as the first winding.
