APPARATUS AND METHODS FOR CAPACITIVE LOAD REDUCTION |
摘要 |
Apparatus and methods for capacitive load reduction are disclosed. In one embodiment, a power amplifier system includes a power amplifier configured to amplify a radio frequency (RF) signal of a first frequency and an envelope tracker configured to control a supply voltage of the power amplifier using an envelope of the RF signal. The power amplifier system further includes an inductor electrically connected between the power amplifier and the envelope tracker and a capacitor electrically connected between the power amplifier and the envelope tracker. The capacitor and the inductor are configured to have a resonance near the first frequency.
