Abstract
A differential amplifier (24, 26, 10 and 12) having a feedback network (30, 34, 32, 36 and 38) for increasing common output without loss of gain. Also disclosed is a constant current source (60), and a level shifting network (48, 50, 52 and 54) for shifting the D.C. level of the output signal to a D.C. voltage substantially near that of second current source (44). An output stage (84, 86, 90, 92 and 94) provides low output impedance, low D.C. bias power consumption and high current drive capability.
