Abstract
A low-noise amplifier includes a first amplification device. The first amplification device includes a control terminal, a first terminal, and a second terminal. The low-noise amplifier also includes a feedback circuit in communication with the control terminal and the first terminal. The feedback circuit compares a voltage, corresponding to an output current associated with the first terminal, with a predetermined reference voltage to generate a bias signal applied to the control terminal for biasing the low-noise amplifier.
