### Common Source Amplifier Circuit

This diagram represents a common source amplifier circuit using a MOSFET. Below is a detailed description of the components and layout of the circuit:

#### Components:

- **V1 (AC Voltage Source)**
  - Voltage: 500 mVrms
  - Frequency: 1 kHz
  - Phase: 0 degrees

- **C1 (Coupling Capacitor)**
  - Capacitance: 0.1 µF

- **RG (Gate Resistor)**
  - Resistance: 1 MΩ

- **RD (Drain Resistor)**
  - Resistance: 3.3 kΩ

- **RS (Source Resistor)**
  - Resistance: 1 kΩ

- **C2 (Source Bypass Capacitor)**
  - Capacitance: 10 µF

- **C3 (Output Coupling Capacitor)**
  - Capacitance: 1 µF

- **RL (Load Resistor)**
  - Resistance: 10 kΩ

- **Power Supply**
  - Voltage: 15 V

#### Circuit Explanation:

- The circuit begins with an AC voltage source (V1) which is coupled to the input of the amplifier through the capacitor **C1**. This capacitor blocks any DC component of the signal, allowing only AC signals to pass through.
  
- The resistor **RG** is connected to the gate of the MOSFET. This resistor is very high in value (1 MΩ) to ensure that it does not affect the DC biasing of the MOSFET and ensures a high input impedance.

- The resistor **RD** is connected to the drain terminal of the MOSFET and is used to convert the AC voltage changes at the drain into voltage changes in the output signal.

- The source resistor **RS** provides negative feedback to stabilize the gain. The capacitor **C2** bypasses RS at AC signals to increase gain while maintaining DC stability.

- The output coupling capacitor **C3** blocks DC from reaching the load, passing only the AC component to **RL**.

- The load resistor **RL** is where the output signal is measured.

This common source amplifier configuration is known for providing high voltage gain and is widely used in signal amplification applications.
