Consider an NMOS device with the I-V characteristics shown below.
(a) Find the common-source small-signal model around the operating point at VDS = 6 V and VGS
= 2.5 V. Note that you will have to add a resistor between the drain and the source in your model,
often denoted as r o .
(b) If this transistor is then used in the circuit below:
What is the small-signal voltage gain, AV= vo /vin?

3. Consider an MMOS device with the I-V characteristics shown below. (a) Find the common-source small-signal model around the operating point at Vos $=6\mathrm{V}$ and Vos $=2.5\mathrm{V}$. Note that you will have to add a resistor between the drain and the source in your model, often denoted as ${\mathrm{I}}_6$ (b) If this transistor is then used in the circuit below: What is the small-signal voltage gain, Av= Vo $\mathrm{V}$ ??
