POWER AMPLIFIER ARRANGEMENT |
摘要 |
An amplifier arrangement includes a class-G amplifier, biased by a first and a second pair of bias voltages, a drive control circuit and a second amplifier (C) biased by the second pair of supply voltages, the drive control circuit (DCD) thereby being adapted to turn on said second amplifier (C) at a higher input signal amplitude than the input signal amplitude at which the current in the class-G amplifier is internally switched over from the first pair to the second pair of bias voltages.
