Abstract
This invention provides a novel high-gain stabilized converter circuit which is adapted to convert emitter coupled logic (ECL) signals for use in gallium arsenide (Ga As) circuits. The novel converter is adapted to be made in gallium arsenide logic on the same chip as the logic circuitry which it is driving. The converter includes a novel differential amplifier having a level shifting network at the active input and a second level shifting network at the reference input to provide a stabilized high-gain circuit which is compensated for variations in temperature and process deviations.
