摘要： A method and apparatus for performing dynamic current scaling of an input current of a voltage regulator are provided. The method and apparatus allow tuning current consumption in various applications, calculating a duration of an activity phase in which various algorithms are executed and activating dynamic current scaling of a regulator if the activity duration is shorter than a programmable threshold. A controller receives a threshold for an activity duration and a window size in which to evaluate the activity duration.

摘要： A system for managing electrical loads includes a plurality of branch circuits, a sensor system, and control circuitry. The sensor system is configured to measure one or more electrical parameters corresponding to the plurality of branch circuits, and transmit one or more signals to the control circuitry. The control circuitry is configured to determine respective electrical load information in each branch circuit based on the sensor system, and control the electrical load in each branch circuit using controllable elements based on the respective electrical load information. The control circuitry transmits usage information, generates displays indicative of usage information, accesses stored or referencing information to forecast electrical load, and manages electrical load in response to identified events. The control circuitry can associate each branch circuit with reference load information, and disaggregate loads on each branch circuit based on the reference load information and on the electrical load in the branch circuit.

摘要： Embodiments of a device and method are disclosed. In an embodiment, a calibration circuit for a temperature sensor circuit includes a current source configured to generate a temperature independent reference current and further includes a voltage window generator circuit. The voltage window generator circuit is configured to generate a voltage window for the temperature sensor circuit using at least the temperature independent reference current. The voltage window is defined by a first reference voltage and a second reference voltage. The voltage window generator circuit is further configured to control a width of the voltage window to include a range of proportional to absolute temperature (PTAT) voltage outputs of a temperature sensor in the temperature sensor circuit.

摘要： A bandgap voltage reference circuit includes first and second transistors (e.g., 3-terminal BJTs or diode-connected BJTs), and a PTAT element (e.g., resistance or capacitance). The first transistor is at a first die location, and operates with a first base-emitter voltage. The second transistor is at a second die location, and operates with a second base-emitter voltage. Each of the first and second transistors may include multiple individual parallel-connected transistors. The PTAT element is operatively coupled to the first and second transistors such that a voltage difference between the first and second base-emitter voltages drops across the PTAT element. The first and second locations are separated by a distance (e.g., 1.5% or more of die length, or such that the respective centroids of the first and second transistor are spaced from one another). Such spatial distribution helps mitigate voltage shift induced by mechanical stress, and is insensitive to process variation.
