ABSTRACT:
An electric amplifier adapted to respond to an input signal of either polarity comprising a first differential amplifier OP1 which is arranged to drive through a load L a current whose value varies with the input but is independent of the load value and a second differential amplifier OP2 arranged to maintain the ratio of the amplifier output potentials relative to a datum potential at a predetermined value so that by appropriate choice of the datum potential and the predetermined ratio value the available output potential swing with a given supply voltage can be maximized.
