![**MOSFET Circuit Analysis**
**Objective:**
Determine the resistor values \( R_D \) and \( R_S \) for a MOSFET circuit to operate in saturation mode, ensuring the drain current (\( I_D \)) is 0.5 mA and the drain voltage relative to the gate (\( V_{DG} \)) is +0.5 V. Given parameters are: threshold voltage (\( V_t \)) = 2 V and transconductance parameter (\( K \)) = 0.5 mA/V².
**Circuit Description:**
The circuit consists of a MOSFET connected to two resistors: \( R_D \) (connected to the drain) and \( R_S \) (connected to the source). Each is powered by a 5 V voltage source.
**Circuit Analysis Steps:**
1. **Identify the Mode:** For saturation, the condition \( V_{GS} > V_t \) and \( V_{DS} \geq V_{GS} - V_t \) must be satisfied. Given \( V_{DG} = 0.5 \, \text{V} \), \( V_{DS} = 0.5 + V_{GS} \).
2. **Find \( V_{GS} \):** Use the drain current equation:
\[
I_D = \frac{1}{2} K (V_{GS} - V_t)^2
\]
With \( I_D = 0.5 \, \text{mA} \), \( V_t = 2 \, \text{V} \), and \( K = 0.5 \, \text{mA/V}^2 \).
3. **Calculate \( R_D \) and \( R_S \):** These resistors must be chosen to meet the current and voltage conditions across the MOSFET.
This approach will provide the values of \( R_D \) and \( R_S \) needed for the circuit operation under specified conditions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faf82ec8f-02f7-492b-b62b-f53ab94e90b9%2F6d2e56cf-6d94-4243-a609-47078d02d36d%2Fkof228m_processed.jpeg&w=3840&q=75)
