摘要：
The present invention relates to an amplifier comprising a first amplification circuit (1) formed of a first transistor (10) and a second amplification circuit (2) formed of a second transistor (11), wherein a first filter (3) having a desired pass-band and a desired attenuation band is connected between the output section of the foregoing first amplification circuit (1) and the input section of the foregoing second amplification circuit (2), thereby reducing noises in the output.
