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 has a fixed impedance regardless of a change of an amplification gain, and a variable gain determination unit comprised of a plurality of transistors is formed at an upper stage in the cascode amplification unit. Accordingly, a change of an input impedance of the cascode amplification unit 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.

摘要： A concentration cooling apparatus for a refrigerator includes a housing which is mounted in a cold air guiding path, and a nozzle which is rotatably supported in the housing, for concentratedly injecting cold air to a region where a high temperature load is generated when the high temperature load is generated in a predetermined region inside a cooling chamber. An infrared sensor is mounted at the front of the nozzle, for sensing the region where the high temperature load is generated. The sensor rotates together with the nozzle and a frost drying sensor is installed on the upper surface of the nozzle, for drying frost on the surface of the infrared sensor. Thus, the reliability of the infrared sensor can be improved by preventing the formation of frost on the surface of the lens of the infrared sensor which detects whether the high temperature load is generated.
