Title:
POWER AMPLIFIER AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/025314
Kind Code:
A1
Abstract:
Embodiments of the present invention disclose a power amplifier and a control method. The power amplifier comprises a current-generating circuit, a first mirror circuit, a power amplifying circuit, and a stacked circuit. The current-generating circuit is used to output a first current according to a received first control voltage. The first mirror circuit is used to mirror current according to the first current, and output a first bias current. The first bias current is used as an input to the power amplification circuit. The power amplification circuit is used to, according to a first radio frequency signal and the first bias current, output a second radio frequency signal whose power meets a preset condition.
