Abstract
A GaAs differential current switch (DCS) logic family is disclosed. Two cross-coupled, push-pull output buffer stages are coupled to the DCS logic circuit to increase the gain and to improve noise margins. The circuit is compatible with other GaAs logic families such as super buffer logic (SBL) or source follower logic (SFFL).
