Amplifier with a strong output current
The present invention relates to an amplifier intended to deliver to a load impedance RL connected between two output terminals of the amplifier an output current Iout which is representative of an input signal (Vin, −Vin) applied to two input terminals of the amplifier, which amplifier includes a f...

| description | The present invention relates to an amplifier intended to deliver to a load impedance RL connected between two output terminals of the amplifier an output current Iout which is representative of an input signal (Vin, −Vin) applied to two input terminals of the amplifier, which amplifier includes a first and a second transistor T and T connected as a differential pair around the load impedance RL. The amplifier according to the invention further includes a third and a fourth transistor T and T which form a differential pair; degenerated by means of a degenerating impedance Req which has a nominal value equal to that of the load impedance RL of the amplifier, which differential pair (T, T) is intended to be controlled by means of a control signal (−Vin/, Vin/), in anti-phase with the input signal (Vin, −Vin). The invention permits to double the output current Iout of the amplifier without, however, increasing its power consumption. |
