Abstract :
An extremely low-power, high-density GaAs logic family is described. Two-phase dynamic FET logic (TDFL) provides all the standard logic functions (NOT, NAND, NOR), and it operates from two nonoverlapping clocks and a single supply. TDFL gates are shown to operate above 750 MHz with an extremely low power dissipation of only 44 nW/MHz gate. TDFL is self-latching, lending itself to highly efficient pipelined architectures, and it is implemented with a standard enhancement/depletion (E/D)-mode MESFET foundry process. Finally, TDFL is directly compatible with static direct-coupled FET logic (DCFL), making its introduction into high-speed systems very straightforward
