Abstract
In order to diminish the risk of oscillation of a broad-band amplifier 20 MHz without considerably reducing the product gain x bandwidth, this amplifier comprises a differential stage T1, T2, T3, T4, a follower stage T5, T6, two common mode feed-back braches T8, T9, T5 on the one hand, T11, T12, T10, on the other hand, and compensation capacitors C1, C2 that are unbalanced, C2 higher than C1, between the supply terminal B and each of the outputs S1, S2 of the differential stage.
