Abstract
The common terminals of the two opposite transistors of a differential stage with an input signal represented by the voltage applied between the bases of the two transistors are connected to ground through two further transistors controlled by the current which passes through the above-mentioned transistors. The output signal is represented by the current which passes through one of said further transistors.
