Threshold and DIBL Voltage vs. Channel Length At a Fixed (Optimum) Lg/Ls Ratio
Performance comparison: assuming minimum DIBL occurs at Lg/Ls = 2
- For each device (Lc = Lg + Ls), Lg/Ls ratio is set at 2 for the HMGFET’s.
- DIBL voltage is indeed much smaller compared to the SMGFET with the same Lc.
