Abstract
A logic circuit including an input transistor receiving the input signal at its emitter, an output transistor in emitter-follower configuration receiving the signal from the collector of the input transistor, a voltage dividing resistor pair connected to the collector of the input transistor, and a feedback circuit conducting the signal produced by the voltage dividing resistor pair back to the base of the input transistor, the output signal being produced at the emitter of the output transistor.
