Abstract

Provided is a low-noise amplifier comprising a source-grounded transistor (M1) having a gate, to which a high-frequency input signal is inputted, a gate-grounded transistor (M2) having a source, to which the high-frequency signal of the drain of the source-grounded transistor is inputted, a load resonance circuit (LoCo) interposed between the drain of the gate-grounded transistor and a power source voltage, a coupling element (C1) interposed between the drain of the source-grounded transistor and the source of the gate-grounded transistor and made effectively open to a DC component and effectively short to a high-frequency component, a bias feeding inductor (Lm1) interposed between the drain of the source-grounded transistor and the power source voltage for feeding a bias voltage to the drain of the source-grounded transistor, and a bias feeding current source (lm2) connected with the source of the gate-grounded transistor for feeding a bias current to the gate-grounded transistor.
