High-density logic techniques with reduced-stack double-gate MOSFETs

We have presented a high-density DG logic circuit technique exploiting the unique V/sub T/ modulation effect through the extended gate-to-gate coupling in high-V/sub T/ symmetrical DG devices. The scheme reduces the number of stacked transistors (hence area/capacitance and standby/dynamic power), and improves performance. The performance improvement and power reduction are evaluated/validated using mixed-mode two-dimensional numerical simulations.
