Elementary logic circuit obtained by means of field effect transistors of gallium arsenide and compatible with the ECL 100 K technology

摘要

An elementary logic circuit obtained by means of Schottky barrier field effect transistors of gallium arsenide includes a differential amplifier, whose first branch, controlled by the input signal E, supplies an output signal S.sub.1, and whose second branch, controlled by a reference signal, supplies an output signal S.sub.2. This circuit further includes two paired level translator stages, the first of which supplies output signal S and the second of which supplies a complementary signal S, the output signal S constituting the reference signal which controls the second branch of the differential amplifier. The circuit can advantageously be used in high-speed IC modules having a lower power consumption, consisting of gallium arsenide and compatible with the circuits realized according to the ECL 100 K technology on silicon.
