Challenge Problems
Push your limits with challenges.
Question 1
Design an active load circuit for a common emitter amplifier that increases its gain from 100 to 150. What would be the necessary specifications for the active load?
💡 Hint: Assess the transformation needed in the I-V characteristics to achieve the gain.
Question 2
If increasing Vcc to 18V led to a power dissipation of 12W in an active load configuration, what measures can be taken to ensure effective thermal management?
💡 Hint: Consider the relationship between power, voltage, and current.
