Challenge Problems
Push your limits with challenges.
Question 1
A common source amplifier has a lower cutoff frequency of 10 Hz and an upper cutoff frequency of 450 kHz. Given a load capacitance of 10 pF, what would happen to the upper cutoff frequency if this capacitance is increased to 100 pF?
π‘ Hint: Consider how higher capacitance affects the circuit's impedance.
Question 2
Discuss how design choices in component values impact the overall frequency response of an amplifier.
π‘ Hint: Think about what happens when you change resistances and capacitances in the context of frequency.
