### What you will learn:

• Software: relatively simple implementation, plus some visualization
• Domain: improve your understanding of how a transistor works

### CMOS Characterization – 1

A CMOS transistor operates in three different regions — cutoff, saturation, and linear. The equations for these are fairly straightforward. Implement these using hard-coded values for parameters that you may need to specify, such as doping concentrations, mobility, etc.

Given input voltages, determine the region of operation and use the appropriate equation to calculate $I_{DS}$

### CMOS Characterization – 2

• Calculate $I_{DS}$ for different values of $V_{GS}$ and $V_{DS}$
• Plot $I_{DS}$ v. $V_{DS}$ for different values of  $V_{GS}$

### CMOS Characterization – 3

• Analyze the differences between N- and P-MOS transistors
• What is the impact of transistor dimensions?
• Read transistor parameters from a file and repeat for different technology nodes.
