Abstract: A power management circuit included in a computer system regulates a voltage level of a power supply node used by other circuits in the computer system. The power management circuit includes a control circuit and multiple phase circuits coupled to the regulated power supply node via corresponding inductors. The control circuit selectively activates particular ones of the multiple phase circuits allowing them source respective currents to the regulated power supply node. The control circuit also selectively activates particular ones of other phase circuits that are external to the power management circuit and coupled to the regulated power supply node via their own corresponding inductors. Once activated, the external phase circuits source respective currents to the regulated power supply node via their corresponding inductors.

Abstract: An amplifier system includes a differential amplifier and a calibration circuit. In response to a calibration operation, the calibration circuit generates a calibration value based on a test output signal generated by the differential amplifier circuit using a test input signal. The calibration value may be used to adjust loading of internal nodes of the differential amplifier circuit to compensate for imbalance in the differential amplifier circuit resulting from variation in manufacturing. By compensating for the imbalance, the offset of the differential amplifier may be reduced, allowing resolution of smaller differential voltages, thereby improving the performance of circuits employing the differential amplifier circuit.

Abstract: A method and apparatus for rapid discharge of power rails is disclosed. A circuit includes a power converter circuit includes an inductor coupled between a switch node and regulated power supply node. A first device is coupled between an input power supply node and the switch node, while a second device is coupled between the switch node and a ground node. The power converter is configured to generate a particular voltage level on the regulated power supply node by controlling the first and second devices. The circuit also includes a control circuit which, in response to receiving a discharge comment, repeatedly activates and deactivates the second device to discharge, via the switch node and the inductor, the regulated power supply node.

Abstract: A voltage regulator circuit included in a computer system may generate a voltage level on a power supply signal using a source power supply signal and based initial values of one or more operation parameters derived from wafer-level test data. One or more operation characteristics of the voltage regulator circuit may be sampled, by a measurement circuit, at multiple time points to generated measurement data. A control circuit may adapt operation of the voltage regulator circuit based on the measurement data.
