摘要： Power supply is facilitated. In accordance with one or more embodiments, a power regulator circuit includes first and second regulators and a controller for controlling operation of the power regulator circuit in standby and normal operational modes. The first and second regulators respectively provide regulated power at main and standby power levels, the standby power level being lower than the main power level. For the standby mode, the controller operates the second regulator for supplying power to an integrated circuit at the standby power level. For transitioning to the normal mode, the controller turns the first regulator on while continuing to operate the second regulator for supplying power to the integrated circuit during a start-up period. After a start-up period (e.g., when the first regulator is up to full power), the controller operates the first regulator for supplying power for operating the processor in a high-frequency mode.

摘要： A reference voltage circuit corrects for bandgap voltage shifts induced during fabrication. The reference voltage circuit generates a reference voltage using first and second base-emitter pairs. The reference voltage circuit sums the voltage across the first base-emitter pair with a difference voltage. During a first time period, the difference voltage is the voltage across the first base-emitter pair minus the voltage across the second base-emitter pair, and during a second time period, the difference voltage is the voltage across the second base-emitter pair minus the voltage across the first base-emitter pair.

摘要： Consistent with an example embodiment, there is a power regulator arrangement with variable current capacity providing power from a power supply to a load having variable demand. As a load, a high-performance microprocessor has several modes of operation. At the highest speed setting, it demands a lot of current. At slower clock speeds and during state retention, the processor has a very low current consumption. Using a single regulator, the current efficiency may be very low during long standby periods. To increase the efficiency even at lower load currents, a scheme is based on parallel operation of multiple regulators having different load ranges, for example, a “low, “medium,” and “high” range regulators. Having knowledge of the load current profile, the regulators can be adjusted such that the peak of the efficiency curve matches the load profile of the regulator. The efficiency of the power regulator arrangement is enhanced throughout the range of power demanded by the load.

摘要： Methods, devices and circuits are provided for power-on-reset circuits with low static power consumption. One such circuit includes a detector that draws current from a supply voltage. The detector detects that the supply voltage has exceeded a trip-point voltage level and then disables current draw from the detector. The detector responds to an enable signal by enabling current draw from the detector. A pulse generator generates a reset signal in response the supply voltage transitioning from a voltage below the trip point voltage level to above the trip point voltage level. A monitor detects that the supply voltage has dropped and provides, in response thereto, the enable signal to the detector to enable current draw from the portion of the detector.

摘要： A digitally controlled hybrid power module is controlled by a programmable controller. The hybrid power module includes a digitally controlled switching supply with an output coupled to an input of a digitally controlled linear voltage regulator. Independent control of switching supply and the linear regulator is provided by the programmable controller, which may be a field programmable gate array (FPGA), microcontroller, or digital signal processor (DSP). The programmable controller may independently control one or more power modules. Each power module may also include enable switching and an associated current clamp for capacitive loads. An output voltage transient suppressor may also be used to control transients, such as those produced under fast switching conditions.
