Patent number: 9105627Abstract: A coil inductor and buck voltage regulator incorporating the coil inductor are provided which can be fabricated on a microelectronic element such as a semiconductor chip, or on an interconnection element such as a semiconductor, glass or ceramic interposer element. When energized, the coil inductor has magnetic flux extending in a direction parallel to first and second opposed surfaces of the microelectronic or interconnection element, and whose peak magnetic flux is disposed between the first and second surfaces. In one example, the coil inductor can be formed by first conductive lines extending along the first surface of the microelectronic or interconnection element, second conductive lines extending along the second surface of the microelectronic or interconnection element, and a plurality of conductive vias, e.g., through silicon vias, extending in direction of a thickness of the microelectronic or interconnection element. A method of making the coil inductor is also provided.Type: GrantFiled: November 4, 2011Date of Patent: August 11, 2015Assignee: International Business Machines CorporationInventors: Michael J.

Patent number: 9052905Abstract: A mechanism is provided for minimizing power consumption for operation of a fixed-frequency processing unit. A number of timeslots are counted in a time window where throttling is engaged to the fixed-frequency processing unit. The number of timeslots where throttling is engaged is divided by a total number of timeslots within the time window, thereby producing a performance loss (PLOSS) value. A determination is made as to whether determining whether the (PLOSS) value associated with the fixed-frequency processing unit is greater than an allowed performance loss (APLOSS) value. Responsive to the PLOSS value being less than or equal to the APLOSS value, a decrease in voltage supplied to the fixed-frequency processing unit is initiated.Type: GrantFiled: September 12, 2012Date of Patent: June 9, 2015Assignee: International Business Machines CorporationInventors: Malcolm S.
