Challenge Problems

Push your limits with challenges.

Question 1

You need to design a common emitter amplifier with constraints of a maximum 20mW power dissipation and a goal of a 150 gain with a supply voltage of 10V. Establish the corresponding resistor values and justify their selection.

💡 Hint: Use the formulas for power and gain calculation accordingly.

Question 2

Determine the effects of doubling the supply voltage on the voltage gain and output swing of a common emitter amplifier, given the original values.

💡 Hint: Rethink all calculations and verify against other constraints.
