Hello. I believe i am getting close but I want to make sure I am doing it right because I'm not yet confident.

Thank you for your time and help.

**Problem Statement:**

Find the Q-point for the diode in Fig. P3.63 using:
(a) The ideal diode model
(b) The constant voltage drop model with \( V_{\text{on}} = 0.6 \, \text{V} \).

(c) Discuss the results. Which answer do you feel is most correct?
(d) Use iterative analysis to find the actual Q-point if \( I_S = 0.1 \, \text{fA} \).

**Circuit Diagram Explanation:**

The circuit in Figure P3.63 consists of:

- A voltage source providing +3 V.
- A series of resistors with values:
  - 3 kΩ connected in series with a diode.
  - 2 kΩ connected parallel to the diode.
  - 2 kΩ connected in series with the parallel branch.
  
- A diode is placed in the circuit oriented with its anode and cathode as labeled in the diagram.

The current \( I \) flows in the loop containing the diode and the resistors.

This circuit is analyzed to find the operating point or Q-point of the diode, which is the point at which the diode operates in a circuit, defined by the diode's voltage and current.
