<p>5-2-1979 1 PHD 78.024 "Transistor amplifier". The invention relates to a transistor amplifier, in particular for input stages, which also allows larger signals to be handled. It comprises two transistor pairs, which are connected in parallel with their bases and collectors, the interconnected emitter electrodes of the one transistor pair receiving an essentially constant direct current and the interconnected emitter electrodes of the other transistor pair an essentially constant direct voltage. The difference of the collector currents of these transistor pairs as a function of the voltage between the bases exhibits varies as a linear function up to larger input voltages (50 mV), so that larger input voltages can also be amplified with low distortion.</p> |
