Abstract
A low-noise amplifier with a first amplification circuit that includes a control terminal, a first terminal, and a second terminal that communicates with a first reference voltage. An impedance load that communicates with the first terminal and a feedback circuit that comprises a current source that communicates with a second reference voltage. A comparator circuit that includes a first input, a second input and an output that communicates with the control terminal. A first impedance that communicates with the current source and the first input and that generates a predetermined reference voltage based on a reference current generated by the current source and a second impedance that communicates with the second input and the impedance load wherein the feedback circuit compares a voltage, based on an output current associated with the first terminal, with the reference voltage to generate a bias signal that is applied to the control terminal.
