摘要： A digitally implemented voltage regulator having including a plurality of slaves coupled in parallel. Each slave includes a switching circuit that intermittently couples an input terminal and an output terminal of the voltage regulator in response to a digital control signal for the corresponding slave. A current sensor in each slave generates a digital first feedback signal derived from the current passing through the corresponding switching circuit. A digital controller receives and uses the digital feedback signals from the plurality of slaves to generate a digital control signal for each slave. The digital controller operates active slaves of the plurality of slaves at determined phase offsets to minimize voltage ripple and maintain the output voltage at the output terminal at a substantially constant level.

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.
