| 主权项 | 1. An apparatus, comprising: a voltage amplitude tracking output stage to generate a first signal representing modulation data and a second signal representing an amplitude of the modulation data, the first signal and the second signal to depend on an output signal, the voltage amplitude tracking output stage to vary a power supply voltage to a gain stage in proportion to the amplitude of the modulation data, the voltage amplitude tracking output stage to determine a bias current for the gain stage based on the amplitude of the modulation data and to apply the bias current to the gain stage. | ||
