ABSTRACT:
A 2-level logic `current injection` circuit topology suitable for heterojunction bipolar transistor (HBT) technology. The circuit requires lower supply voltage headroom and demonstrates smaller propagation delay than conventional 2-level emitter coupled logic/current mode logic (ECL/CML). Master-slave flip-flop circuits have been fabricated in AlGaAs/GaAs, HBT. Test results indicate that the circuits are fully functional at 10 Gbit/s and an operating clock frequency as high as 20 GHz is recorded.
