Abstract
An amplifying device includes a current generating circuit, a bias amplifying circuit, and a compensation circuit. The current generating circuit is configured to generate an internal current based on an internal voltage. The bias amplifying circuit, connected to the current generating circuit, is configured to output a bias current generated by amplifying the internal current to a power amplifying circuit. The compensation circuit, connected to the current generating circuit, is configured to adjust the internal voltage based on a bias voltage of the power amplifying circuit.
