摘要： Exemplary embodiments of the invention include a request received to change a TX output power setting or a frequency channel setting. In response, the requested TX output power setting is used to generate a TX output signal in the proper frequency channel. Handset circuitry makes OOB power measurements, the results of which are used to determine a VCC2 setting. The VCC2 setting is a setting that results in an MPS requirement just being met. The VCC2 setting is stored in association with the TX output power and frequency channel setting. The determined VCC2 setting is also used to set the VCC2 supply voltage for the power amplifier. Once set, VCC2 remains fixed until the next request. Each individual handset uses this Adaptive Average Power Tracking (AAPT) method, thereby reducing its VCC2 voltage during operation and conserving power. Because each handset uses AAPT, factory calibration to account for unit-to-unit variations in transmitter circuitry performance is avoided.

摘要： A dynamic power supply for N amplifiers includes first and second power boost circuits which temporarily boost the positive or negative power supply rail, respectively. A control circuit monitors amplifier output signal levels and provides power boost control signals to the power boost circuits, which temporarily raise the positive supply voltage above the nominal voltage level in tandem with the highest output signal from the N amplifiers and lower the negative supply voltage below the nominal voltage level in tandem with the lowest output signal level from the N amplifiers. The power boost circuits each may be coupled to a reservoir capacitor from which current is drawn to provide the power boost. When inactive, the reservoir capacitors charge up from the respective power supply rails. The dynamic power supply is well suited for audio amplification systems.

摘要： An apparatus for powering a wireless peripheral includes a controller and a power management circuit. The controller is configured to determine the strength of wireless signals received by the peripheral. The power management circuit selectively powers the peripheral with either an external power source or a combination of the external power source and an internal power source included in the wireless peripheral. If the wireless signal strength is weak, the power management circuit uses both the internal an external sources to power the peripheral. This allows the wireless peripheral to boost its transmit power, even though its power requirement may exceed that available from the external source. If the wireless signal strength is strong, the power management circuit uses only the external source to power the peripheral. When this occurs the internal power source may also be simultaneously charged by the external power source.
