Off-State Current vs. Gate or Channel Length for Different (Fixed) Values of S-Gate Length
Investigation
- Plot off-state current against gate or channel length at each fixed S-gate length.
Major features
- Leakage current is reduced by orders of magnitudes for the same technology node, partially due to the elevated threshold at decreasing Lg/Ls ratio.
- The Ioff–Lc curve exhibits an extended flat region at larger Ls.
Benefits
- With reduced leakage current, it gives more room for other design considerations.
