**Transistor Circuit Analysis**

For the circuit shown, assume that \( V_o = 3V \) and that the transistor is described as follows:

\[ Kn = 1250\mu A/V^2 \]
\[ V_{TN} = 1V \]
\[ \lambda = 0.10 \, V^{-1} \]

**Tasks:**

a) Determine the small signal parameters for the transistor.  
b) Draw the small signal model.

**Circuit Diagram Explanation:**

- **Voltage Source:** The circuit includes a 5V DC power supply.
- **Resistors:** There are two resistors in the circuit:
  - A 5kΩ resistor connected between the drain of the transistor and the 5V power supply.
  - A 1250Ω resistor connected between the source of the transistor and ground.
- **Transistor:** An n-channel MOSFET with the gate connected to the input voltage \( V_{in} \). The drain is connected to the 5kΩ resistor and the output voltage \( V_{o} \). The source is connected to the 1250Ω resistor and ground.

This information provides the foundational criteria for analyzing the small signal parameters and constructing the small signal model of the transistor as requested.
