摘要： In order to feed to the converter on the load side of an intermediate-link frequency converter a frequency control signal (fI(S)*) which is formed by means of an angle controller (RW) from the difference of an angle reference value (wi(F)*) and a corresponding actual value (wI(F)), an actual value of the phase current is required which, for stable operation, must not contain heavy harmonics in stable operation nor must not be damped excessively dynamically by smoothing. Therefore, the measured actual angle value (wI(S)) is fed as the reference value of a servo controller (RS), to the output of which the integral (wI(S)*) of the frequency control quantity is added and the output of which is fed back to the input of the servo controller (RS).

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.
