Abstract: Some embodiments include apparatuses and methods of using such apparatuses. One of the apparatuses includes a control circuitry to generate error information based on a value of the feedback voltage generated from an output voltage, generate output information to control a power switching unit based on the error information provided to a forward path in the control circuitry, and adjust a gain of the forward path based on a gain factor computed based at least in part on a first value of the output information in order to cause the output information to have a second value. The control circuitry also computes a value of correction information when the output voltage is within a target value range, and adjusts the control information, based on the correction information, when the output voltage is outside the target value range.

Abstract: A configuration interface bus may be coupled to components of a physical layer (PHY) device. A configuration controller may be coupled with the configuration interface bus and may receive an input signal representing a power state of the PHY device. The configuration controller may further identify a set of instructions that correspond to the input signal and may transmit configuration data via the configuration interface bus to one or more of the components of the PHY device in response to an execution of the set of instructions. The operation of the one or more components of the PHY device may be based on the configuration data.

Abstract: Some embodiments include apparatus and methods having a node to provide a signal, and a control unit arranged to control a value of an output voltage at an output node on an output path based on a duty cycle of the signal and a value of an input voltage. The control unit can also be arranged to cause a change in a resistance on the output path in order to determine a value of a current on the output path based at least on the change in the resistance.

Abstract: Methods and systems to regulate a voltage with multiple selectable voltage regulator (VR) modes, using multiple corresponding circuits and/or a configurable circuit. The circuit may be configurable for one or more of a power-gate VR mode, a switched-capacitor VR (SCVR) mode, and a linear mode, such as a low drop-out (LDO) VR mode. A feedback controller, such as a proportional-integral-derivative (PID) controller, may configure and/or control a multi-mode VR for a selected VR mode. The feedback controller may select a VR mode based on a reference voltage and voltage ranges associated with the VR modes. The circuit may be configurable as banks of VRs, and the controller may be implemented to transition between VR modes by switching sub-banks between modes until the transition is complete.
