摘要： An audio communication unit comprises a receiver for receiving an audio signal, a sigma-delta modulator operably coupled to the receiver and arranged to modulate the received audio signal, and a class-D amplifier stage operably coupled to the sigma-delta modulator and arranged to amplify the modulated received audio signal. One or more feedback path(s) is/are arranged from an output of the class-D amplifier stage to the sigma-delta modulator. The provision of one or more feedback path(s) from the output of the class-D audio amplifier to the sigma-delta modulator facilitates smaller die size; higher power efficiency and power supply rejection ratio/intermodulation cancellation performance.

摘要： A voltage regulator for providing a voltage regulated output to a load comprises a first loop and a second loop. The first loop comprises a first active device coupled to a first pass device and configured to provide a first, relatively high current output to the load. The second loop comprises a second active device coupled to a second pass device and configured to provide a second, relatively low current output to the load.In this manner, when the inventive concept is applied to low drop-out regulators, the provision of two independent loops reduces dramatically the quiescent current provided by the voltage regulator under low load conditions.

摘要： A power amplifier module comprises a power amplifier circuit having an output power level controlled by a power supply voltage. A power supply transistor controls the power supply to the power amplifier circuit from a drive signal which is received from a drive circuit. The drive circuit generates the drive signal in response to a power level input signal, which specifically may correspond to a power ramping for a GSM cellular communication system. The power amplifier module furthermore comprises a detection circuit which determines an operating characteristic of the power supply transistor. The operating characteristic is preferably a saturation characteristic. A control circuit controls the drive signal in response to the operating characteristic. The control circuit preferably controls the drive signal such that the power supply transistor does not enter the linear region for a Field Effect Transistor and the saturated region for a bipolar transistor.
