Question 1
Design a common emitter amplifier with specific gain requirements, considering the constraints of power dissipation and output swing. Detail the steps taken in your design process, including the calculations for all biasing resistors and coupling capacitors.
💡 Hint: Start with identifying all parameters and resolve them systematically.
Question 2
For a common emitter amplifier with a supply voltage of 15V and a target output swing of 8V, calculate the appropriate biasing resistors. Assuming IC = 2mA, find the necessary resistance values.
💡 Hint: Consider the voltage drop across each component in your solution.
