摘要： A voltage regulator is described for microelectronic devices using dual edge pulse width modulated control signal. In one example a first digital duty cycle value is received from a voltage controller and a pulse width modulated waveform is generated in response to the first duty cycle value, the waveform comprising a plurality of pulses with a modulated width. The waveform is applied to a voltage generator to generate a supply of power at a voltage determined by the duty cycle of the waveform. A second digital duty cycle value is received from the controller, and the leading edge of a subsequent pulse of the waveform is advanced if the second digital duty cycle value is greater than the first digital duty cycle. The trailing edge of the subsequent pulse of the waveform is advanced if the second digital duty cycle value is less than the first digital duty cycle value.

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.
