**Problem 4:**

The pMOSFET in the circuit has:

- \( k'_p = 60 \, \mu A/V^2 \)
- \( L = 0.8 \, \mu m \)
- \( \lambda = 0 \)
- \( V_t = -0.7 \, V \)

If the desired \( V_D = 3.5 \, V \), \( I_D = 115 \, \mu A \), determine the required values of \( R \) and \( W \).

**Diagram Explanation:**

The circuit diagram shows a pMOSFET transistor. A direct voltage (\( V_{DD} \)) of 5 V is connected to the drain of the pMOSFET. The source is connected to a point labeled \( V_D \). A resistor \( R \) is connected from the source to the ground. Current \( I_D \) flows through the resistor. 

You need to calculate the values of the resistor \( R \) and the transistor width \( W \) to meet the given conditions for \( V_D \) and \( I_D \).
