Challenge Problems
Push your limits with challenges.
Question 1
Design an amplifier circuit using two cascaded Common Emitter stages. Calculate overall gain and analyze potential loading effects.
💡 Hint: Remember to factor in resistances in real scenarios!
Question 2
In a scenario where cascading two amplifiers reduces bandwidth, suggest how introducing buffers could reverse this effect and provide calculations for expected performance.
💡 Hint: Check how cutoffs change with this new setup!
