    摘要: A method and apparatus for current detection for microelectronic devices using source-switched sensors. An embodiment of a current detector for a microelectronic device includes a first voltage sensor and a second voltage sensor. The first voltage sensor is to measure a first voltage of the microelectronic device during a first time period and a second voltage of the microelectronic device during a second time period. The second voltage sensor is to measure the second voltage during the first time period and the first voltage during the second time period. A voltage value is equal to the sum of the first voltage measured by the first sensor plus the first voltage measured by the second sensor, minus the sum of the second voltage measured by the first sensor plus the second voltage measured by the second sensor. Other embodiments are also described and claimed.

    摘要: Methods and apparatuses provide voltage regulation for a processor. Control or configuration parameters for a voltage regulator (VR) are provided digitally over a configuration bus to a VR controller. The parameters may be provided directly from a storage element, or via a processing element or processor core. Based in whole or in part on the parameters, the VR controller provides an output control signal to affect a power output from a power converter to the processing element. In one embodiment, the VR controller is integrated onto the same IC as the processing element.

    摘要: An apparatus includes a substrate, a target timing circuit, a leakage timing circuit, and a control unit. The target timing circuit and the leakage timing circuits are formed on the substrate. The target timing circuit has a target timing circuit frequency related to a target frequency. The leakage timing circuit has a leakage timing circuit frequency related to a leakage current. The control unit maintains a substantially constant ratio between the target timing circuit frequency and the leakage timing circuit frequency. A method includes generating a first signal related to a target circuit frequency, generating a second signal related to a leakage current, and adjusting a control signal applied to a substrate to maintain a substantially constant frequency ratio between a first signal and the second signal.
