Design a common emitter amplifier for a small audio application targeting a gain of 40. Given a power supply of 10V and a maximum power dissipation of 20mW, outline the steps to choose appropriate resistor values.
💡 Hint: Remember that understanding gain and power dissipation involves balancing act between V, I, and RC.
You need to design an amplifier circuit that uses a silicon BJT with β = 150. Calculate the necessary parameters if you want a quiescent current of 1mA, and discuss how the output swing will be affected by your choices.
💡 Hint: Think about how the quiescent current and beta affect the biasing network.
