Determine the operating point (IDQ and VGSQ) for a self-bias depletion-type MOSFET circuit.

Here's how to determine the operating point for the self-bias depletion-type MOSFET circuit:

a) Determine $I_{DQ}$ and $V_{GSQ}$.

Step 1: Write the relationship between $V_{GSQ}$ and $I_{DQ}$ for a self-bias configuration.
For a self-bias configuration, the gate current $I_G$ is approximately zero, so the voltage drop across $R_G$ is zero. This means $V_G = 0 \text{ V}$.
The source voltage $V_S$ is given by $I_{DQ} \cdot R_S$.
The gate-source voltage $V_{GSQ}$ is $V
