Challenge Problems
Push your limits with advanced challenges
Design a common gate amplifier with a specified input impedance of 300Ω and output swing of ±3V using a supply of 9V. Discuss the challenges faced in achieving this.
💡 Hint: Consider how resistors affect the overall circuit beyond just the values.
Given a scenario where the output swing is insufficient, propose modifications to the existing circuit components to meet specification without altering the topology.
💡 Hint: Think about what changes would offset the limitations encountered.
