equal and opposite, namely to increase the number of South I, IC2 is necessary to reduce the number. Thus the current flowing through the change amount of Re is zero (i.e. Ue 0, which is adjacent to no effect on the presence of differential mode signals, i.e., no negative feedback), does not affect the differential mode amplification. Therefore, the differential-mode signal words,
