Question

For the circuit provided in Figure 4-32 (p. 194), find ID and VDS. VBias = 2.5V, VDD = 5V, RL = 1kΩ, Vt = -0.3V, kp = 100uA/V2

### Exercise 4-32 (Exercise 4-16)

This diagram represents a simple transistor circuit. 

#### Components:
- **Transistor**: Depicted with three terminals.
  - The gate terminal is connected to a voltage source labeled \( V_{\text{BIAS}} \).
  - The drain terminal is connected to a voltage supply labeled \( V_{\text{DD}} \).
  - The source terminal is connected to a resistor.

- **Resistor**: Labeled \( R_L \) and connected to ground.

- **Current**: The current flowing through the transistor from drain to source is indicated as \( I_D \).

#### Explanation:
- **\( V_{\text{BIAS}} \)**: The bias voltage applied to the gate of the transistor to control its operation.
- **\( V_{\text{DD}} \)**: The supply voltage for the circuit.
- **\( I_D \)**: The current flowing through the load resistor \( R_L \) to ground.
- **\( R_L \)**: Load resistor connected to the source terminal of the transistor, influencing the output current and voltage.

This circuit illustrates the basic operation of a field-effect transistor (FET) used as a switch or amplifier in electronic circuits. The gate voltage \( V_{\text{BIAS}} \) controls the conduction between the drain and source terminals.
