ABSTRACT:
The invention relates to a digitally gain-controlled amplifier including a transconductance stage provided with means for producing, at each of its N current outputs, a current (Itr) having a variable component which is representative of the analog input voltage. The amplifier also includes a switching stage comprising N switches each controlling the activation or deactivation of one of the N current outputs of the transconductance stage. Finally, the amplifier has a current/voltage conversion stage having one voltage output constituting the analog output of the amplifier and supplying a voltage which is representative of the currents received at its N current inputs.
