Given a common base amplifier with a supply voltage of 10V, resistance values for biasing of 20kΩ each, and a β of 200, calculate the maximum output swing based on your earlier lessons.
💡 Hint: Focus on biasing effects and saturation thresholds for precise swing limits.
For a common gate amplifier, derive the current gain knowing the input current is 0.5mA and the output current is 4mA. Verify it mathematically.
💡 Hint: Map out the relationships between input and output currents carefully.
