Laboratory 3/4


Discuss the statement:


Those inverters, which are mostly built by PMOS transistors, have worse electrical characteristics than those which mainly consist of NMOS semiconductors due to switching losses which are remarkable higher at PMOS structures.


Polysilicon can go under M1 without short.
A short connection in the center could be used.

Why are the exports (M2 contacts) stretching beyond width of cell?

Precision of measurement
1.16 ns - 1.13ns =
More digits are needed.
0.34534 ns
It can be an interpolated value: 2..3 digits accuracy.

Polysilicon delay only active with conservative RC.

Open questions: ambiguity
How much time did you spent?
