Abstract: A system (100) that includes a regulator (101) unit is disclosed. The regulator unit (200) includes first and second phase units (201a, 201b) whose outputs are coupled to a common output node (204). Each of the phase units (201a, 201b,...) may be configured to source current to the output node in response to the assertion of a respective clock signal (208a, 208b,...) in order to generate a regulated supply voltage (204). Each phase unit (201a, 201b,...) includes a respective transconductance amplifier (301) configured to generate a respective demand current (314) dependent upon a reference voltage (207) and the regulated supply voltage (204).

Abstract: A semiconductor device package is described that includes a power consuming device (such as an SOC device). The power consuming device (120) may include one or more current consuming elements. A passive device (100) may be coupled (110) to the power consuming device. The passive device includes a plurality of passive elements formed on a semiconductor substrate. The passive elements are arranged in an array of structures (102) on the semiconductor substrate. The power consuming device and the passive device are coupled using one or more terminals (110). The passive device and power consuming device coupling may be configured in such a way that the power consuming device determines functionally the way the passive device elements will be used.

Abstract: A method and apparatus for monitoring instantaneous load current is disclosed. In one embodiment, an integrated circuit includes a voltage regulator and at least one functional unit implemented thereon. The voltage regulator includes a supply circuit configured to provide a voltage to the functional unit, and a sense circuit configured to determine an amount of current provided to the functional unit by the supply circuit. The sense circuit may determine the instantaneous load current being provided to the functional unit. An indication circuit is configured to provide, to the functional unit, an indication of the amount of current supplied thereto by the supply circuit.
