    Abstract: A UE communication device is provided having a transmitter architecture that transmits SRS transmissions and PUSCH transmissions. A reference mode chosen from a LPM, an MPM and an HPM is selected based on a present power mode of the SRS transmission or based on a predicted power mode that the PUSCH transmission following the present SRS transmission will likely operate in. The transmitter architecture has an exemplary extended switching point structure allowing the RPD between the SRS transmission used for pre-quarter selection and the subsequent PUSCH transmission applying the pre-quarter to be minimized.

    Abstract: A voltage regulator includes a current bridge and first and second current paths coupling a current mirror to respective first and second voltage-to-current converters. The current mirror controls a second current dependent on a first current. The first voltage-to-current converter controls the first current dependent on either a reference voltage or a feedback voltage derived from the regulator's output voltage, and the second voltage-to-current converter controls the second current dependent on the other of the feedback and reference voltages. Voltage-to-current conversion by the first converter is independent of voltage-to-current conversion by the second converter. An output transistor stage coupled to the second current path controls the output voltage dependent on the voltage in the second current path indicative of a deviation of the second current from a target current value dependent on the reference voltage.
