ADAPATIVE POWER AMPLIFIER |
| 摘要 |
Exemplary embodiments are related to an envelope-tracking power amplifier. A device may include a first transistor of a plurality of transistors in a stacked configuration configured to receive a supply voltage varying with an envelope of a radio-frequency (RF) input signal. The device may further include a second transistor of the plurality in the stacked configuration coupled to a reference voltage and configured to receive a dynamic bias voltage varying inversely proportional to the supply voltage. |
