ABSTRACT:
In a high gain differential amplifier, in order to obtain a high gain-band product, this amplifier is provided with a controlled feedback in current. In each of the channels of the amplifier, a current generator connected to the output of the amplifier draws a current through the load resistor of the channel. Each generator is constituted by a current mirror. Application to fast analog circuits.
