Abstract
In a circuit arrangement for amplifying a television signal, having, arranged between an input (2, 3) and an output (6) , a differential amplifier (1) comprising two emitter-coupled transistors (101, 102), high linearity and stability is obtained in spite of a low supply voltage, a high drive and manufacture in a method which produces transistors with a comparatively low 'Early-voltage', by a combination of at least one ohmic resistor (103, 104; 202) arranged in the emitter branch of the transistors (101, 102) and a resistive feedback network (7) for feeding back a signal from the output (6) to the input (2, 3).
