| Zusammenfassung: | Amplifier includes a differential amplifier(A) and a 1st collector follower amplifier(Q3) connected to the output terminal of the differential amplifier. A 2nd collector followeramplifier(Q4) is provided whowe input terminal is connected to the common impedance of the differential amplifier to receive one part of the voltage thereacross, and the output terimnal of the 2nd amplifier(Q4) is connected to the output terminal the 1st collector follower amplifier to reduce the common mode gain of the differential amplifier. |
