ABSTRACT:
A circuit for amplifying electrical signals, particularly for devices for transmitting frequency-modulated emitter coupled logic (ECL) broad-band signals by means of coaxial lines utilizes a plurality of ECL logic elements as amplifier stages. The input of each logic element is connected to a bias voltage and is charged by means of a coupling capacitor with the signal to be amplified. The circuit amplifies electrical signals to ECL level with an improved signal pulse duty factor.
