ABSTRACT:
Described is an improved electrical amplifier including a circuit arrangement which biases the amplifier so that current in an output stage of the amplifier is constant even though its load current varies. The circuit arrangement is configured so that the biasing current in the output stage is varied dynamically, thus compensating for changes in the current of the load which the amplifier drives.
