ABSTRACT: In a differential amplifier with single-ended drive in accordance with the invention a balancing impedance is arranged between the base of the transistor connected to the signal input and the common point of the two emitters of the transistors which form a differ- ential pair. The capacitance value of the capacitor which forms at least part of the balancing impedance is at least substantially equal to the capacitance value of the stray capacitance of the collector-substrate (or "earth") junction of the transistor which forms the cur rent source. This results in a symmetry of the capaci- tances between the input and the common point and between the common point and earth via the transistor forming the current source, which yields an improved balance in the output signals on the output terminals and a flat fre- quency response of the differential amplifier for higher frequencies.
