Abstract
A high speed gallium arsenide (GaAs) integrated circuit is provided which converts GaAs input or source signals to voltage levels for directly driving emitter coupled logic (ECL) circuits. The high speed GaAs level converter comprises a level shifting network at the input, two stages of differential amplification and a novel source follower output stage.
