Assuming $V_{tn} = |V_{tp}| = 1V$ determine the region of operation of each MOS transistor. - 5V - 4V + 4V - 5V + 2V + 1V + 3V + 1V

Step 1
Therefore, the gate-source voltage is $V_{GS} = -5V - (-4V) = -1V$. Since $V_{GS} < V_{tn}$, the transistor is in the cutoff region. Show more…

The PMOS transistor in Fig. P5.40 has Vtp = -0.4 V. As the gate voltage vG is varied from +2 V to 0 V, the transistor moves through all of its three possible modes of operation. Specify the values of vG at which the device changes modes of operation. +2 V vG +0.8 V Figure P5.40

Find vDS for circuits (a) and (b) and find vSD for circuits (c) and (d). In all cases, assume that the NMOS transistors have Vtn = 1 V and Kn = 0.5 mA/V^2. Assume that the PMOS transistors have Vtp = 1 V and Kp = 0.25 mA/V^2. Note that because we use vSG for PMOS transistors, the threshold voltage will be positive.
