Challenge Problems
Push your limits with challenges.
Question 1
Assume a common emitter amplifier has a load resistor of 1.5 kΞ© and the DC supply voltage is 12V. If the thermal voltage is 26 mV, derive the maximum theoretical gain for this configuration.
π‘ Hint: Make sure to convert thermal voltage correctly and look at the concept of maximum gain.
Question 2
Propose a design modification for a common source amplifier experiencing low voltage gain. Detail how you would implement an active load and its expected impact.
π‘ Hint: Think about why using an active element can affect gain positively.
