摘要： A variable gain amplifier (VGA) having stable input impedance matching and a stable noise figure in spite of a variation of an amplification gain is provided. In an embodiment of the VGA, a first stage of a cascode amplification unit (3200) has a fixed impedance regardless of a change of an amplification gain, and a variable gain determination unit (220) comprised of a plurality of transistors is formed at an upper stage in the cascode amplification unit (3200). Accordingly, a change of an input impedance of the cascode amplification unit (3200) due to the change of the amplification gain is minimized. In another embodiment of the VGA, an amplification gain of an amplification unit is controlled by adjusting a voltage applied to the amplification unit by controlling a current to be output by a current supply source, and stable input impedance matching and a stable noise figure are obtained.
