In a gain control circuit (GCC), a plurality of parallel-arranged differential pairs (DP1,DP2 . . . DPN) is unbalanced as a function of a gain control signal (Vagc). Furthermore, the gain of individual differential pairs (DP1,DP2 . . . DPN) is reduced when the unbalance is increased, and vice versa. Accordingly, a favorable performance in terms of noise and distortion can be obtained. |
