摘要： Disclosed are systems, devices, circuits, components, mechanisms, and processes in which a switching mechanism can be coupled between components. The switching mechanism is configured to have an on state or an off state, where the on state allows current to pass along a current path. A monitoring mechanism has one or more sensing inputs coupled to sense an electrical characteristic at the current path. The electrical characteristic can be a current, voltage, and/or power by way of example. The monitoring mechanism is configured to output a reporting signal indicating the sensed electrical characteristic. The monitoring mechanism can be integrated with the switching mechanism on a chip.

摘要： A voltage regulator has an input terminal, an output terminal, a first transistor to intermittently form an electrical circuit between the input terminal and the output terminal, a rectifier connecting an intermediate terminal in the electrical circuit between the input terminal and the output terminal to ground, a controller that drives the first transistor, and a capacitorless filter. Capacitance for the filter function can be provided by a capacitor, e.g., the input capacitor of the load, located in the load chip or on the same printed circuit board as the load chip. The capacitorless filter can include an inductor connected between the intermediate terminal and the output terminal, or the inductance can be provided by parasitic effects in the connections between the voltage regulator and load.

摘要： A digital voltage regulator has an input terminal (20) coupled to an input voltage source (12), an output terminal (22) coupled to a load (14), and a plurality of switching circuits (24) to alternately couple and decouple the input terminal (20) to the output terminal (22). An estimated current is calculated for each switching circuit (24), each estimated current representing a current passing through an inductor (34) associated with the switching circuit (24). A total desired output current to pass throught the inductor (34) is calculated which will maintain an output voltage at the output terminal (22) substantially constant. The switching circuits (24) are controlled based on the estimated current and the total desired output current so that a total current passing through the inductor (34) is approximately equal to the total desired output current.

摘要： A sensor for measuring a current passing through a load. The sensor has a power transistor having a first terminal connected to substantially constant voltage and a second terminal connected to the load. The sensor can sample a voltage difference with a variable capacitor, and a controller can be configured to cause a variable capacitor in the current sensor to have a capacitance inversely proportional to a resistance of the power transistor, whereby a charge stored on the variable capacitor is proportional to the current passing through the power transistor when the sampling switches are opened. A comparator can compare the current through the power transistor to a known reference current to generate a digital output signal. The sensor can include a power transistor, reference transistor and amplifier connected and configured so as to generate a signal on a reference line having a current of known proportion to the current passing through the load.
