**Question 1: Factors Limiting the Gain of a Common Source Amplifier**Discuss some of the factors that limit the gain of a common source amplifier. Why can't the gain be made arbitrarily high simply by increasing the ratio of the drain resistor to the source resistor?**Explanation and Details**:The gain of a common source amplifier is primarily influenced by several factors including device parameters, load resistance, and power supply constraints. Merely increasing the ratio of the drain resistor to the source resistor does not result in an unlimited gain due to the following reasons:1. **Internal Device Capacitance**: High frequencies introduce capacitive effects within the transistor, reducing the amplifier's bandwidth and, consequently, its gain.2. **Transistor Parameters**: The transconductance (\(g_m\)) of the transistor and its output conductance (\(g_{ds}\)) can limit the maximum attainable gain.3. **Thermal Noise and Distortion**: Higher resistance values can increase noise levels and lead to signal distortion, impacting the performance of the amplifier.4. **Voltage Compliance**: The voltage drop across increased resistance may limit the headroom for the output signal, impacting linearity and distortion.Understanding these limitations is crucial for designing amplifiers with optimal performance.
