Abstract
An active circuit is disclosed including an integrated circuit having at least one amplification stage comprising an FET. At least one negative feedback transistor is provided of the same conduction type as the amplifying transistor, with the drain-to-source path of the negative feedback transistor coupled in series between the drain and gate of the amplifying transistor. At least one biasing transistor of the same conduction type as the amplifying transistor are provided to bias the gate of the negative feedback transistor. The drain of the at least one biasing transistor is connected to a current source furnishing a current having a given ratio to the power supply current of the amplifying transistor. This circuit permits precise control of the small-signal resistance of the feedback transistor.
