A power management circuit for an electronic device sequentially activates and/or deactivates electronic circuits of the electronic device. The power management circuit provides a first group of one or more circuit power management signals to activate and/or deactivate a first electronic circuit from among the electronic circuits. Thereafter, the power management circuit provides a corresponding power management signal from among a second group of the one or more circuit power management signals that corresponds to a portion of the first electronic circuit that has been activated and/or deactivated by the first group of the one or more circuit power management signals to activate and/or deactivate a portion of a second electronic circuit from among the electronic circuits. The power management circuit continues to sequentially provide each of the one or more circuit power management signals in a similar manner until the electronic circuits of the electronic device have been activated and/or deactivated.

Power management circuit for an electronic device

An integrated circuit has a first circuit portion on a first level and a second circuit portion on a second level different from the first level. The first circuit portion includes a first cell having a first voltage value at a first node and a second voltage value at a second node. The second circuit portion includes a second cell coupled with the first cell, the second cell being selectively controllable to supply a voltage to the first cell based on an instruction to supply the voltage. The instruction to supply the voltage is based on a determined mismatch between the first voltage value and the second voltage value being greater than a predetermined threshold value.

Integrated circuit having voltage mismatch reduction

An integrated circuit comprises a first circuit portion comprising a plurality of first cells, each first cell comprising a first transistor having a first voltage value at a first node, and a second transistor having a second voltage value at a second node. A second circuit portion comprises a plurality of second cells. The second cells are individually coupled with a corresponding first cell of the plurality of first cells. The second cells are selectively controllable to supply a voltage to one or more of the first cells based on an instruction to supply the voltage. The instruction to supply the voltage is based on a determined mismatch between the first voltage value and the second voltage value being greater than a predetermined threshold value.

The present disclosure relates to a differential sense amplifier comprising first and second cross-coupled inverters with first and second complimentary storage nodes. A first current control element changes a current through the first cross-coupled inverter based upon an output of a second cross-coupled inverter, and a second current control element changes a current through the second cross-coupled inverter based upon an output of the first cross-coupled inverter. Other devices and methods are also disclosed.
