1 Metal–Oxide–Semiconductor Field-Effect Transistor: Additional Concepts
Chapter 12 Metal–Oxide–Semiconductor Field-Effect Transistor: Additional Concepts .

2 12.1.1 Nonideal Effects…..subthreshold

3 12.1.2 Nonideal Effects…..channel length modulation
Where is the actual drain current and is the ideal drain current. Since is a function of , is now also a function of even though the transistor is biased in the saturation region.

4 12.1.3 Nonideal Effects…..mobility variation
Where and are constants determined from experimental results.

5 12.1.4 Nonideal Effects…..velocity saturation

6 12.2 MOSFET Scaling See Table 12.1
