Abstract

The authors discuss the design, fabrication, and performance of the first small-scale integrated logic family, including a current-mode-logic (CML) inverter, OR/NOR, NAND/OR, exclusive OR/NOR gates, and master-slave flip-flops, implemented using self-aligned AlGaAs/GaAs heterojunction bipolar transistors (HBTs). The HBTs incorporated in the ICs (integrated circuits) are based on a 2.5-μm emitter design rule and exhibit a current gain of 40, a cutoff frequency of 50 GHz, an estimated CML gate-propagation delay time of 24.7 ps, and a non-threshold-logic gate-propagation delay time of 12.3 ps. Successful operation of the logic circuits has been predicted using a SPICE-F simulator and verified experimentally.
