ABSTRACT:
A differential amplifier has at least two pairs of transistors functioning as current dividing circuits in addition to two other conventionally employed current dividing circuits in this type of amplifier. The signal current components flowing through the two additional current dividing circuits surffer no substantial distortions as do those flowing through the conventional current dividing circuits. The output current of the differential amplifier is a sum of these signal components. Accordingly, the less the proportion of the distorted signal components to the undistorted ones is, the freer the differential amplifier from waveform and high frequency distortion becomes.
