Have one more question:
I did 3 analysis in which 1st case- all the conditions were typical- typical Vdd, Temp, Vth and Leff.
In other one, I kept Temp 125c, Vdd decreased by 10%, Vth increased by 10% and Leff unchanged.
and in 3rd one, I kept Temp 125c, Vdd decreased by 10%, Vth increased by 10% and Leff increased by 10%.
Technically, if I increase Leff, then the circuit performance slows down even more. But surprisingly, I found 2nd case slower than 3rd one. Cant understand why!?
Can anyone tell me?
