Abstract :
In this work, a novel and straightforward enable/disable GaAs MESFET Differential Logic (EMDL) structure is presented. EMDL is compatible with DCFL and some reported MESFET differential logic families, like DPTL, DCVS and DC/sup 2/FL. No power dissipation during the standby state, fewer transistors per logic function and noise immunity are its more interesting features. The EMDL can be efficiently applied in both synchronous and asynchronous designs. EMDL iterative network micropipeline applications are detailed. An 8-bit ripple carry adder was successfully fabricated and tested verifying the EMDL functionality and performance characteristics.
