Abstract
A low-noise amplifier comprises a first amplification circuit that includes a control terminal and a first terminal. An impedance load communicates with the first terminal. A feedback circuit outputs an output current to the first terminal and that generates a bias current, which is output to the control terminal and is based on a difference between the output current and N times a reference current, where N is greater than zero.
