Challenge Problems
Push your limits with challenges.
Question 1
Given a cascode amplifier with C_gs1 = 12 pF and C_gd1 = 7 pF and a voltage gain of -40, calculate the new input capacitance.
💡 Hint: Substitue the values carefully into the formula.
Question 2
Investigate how changing small-signal parameters affects both gain and capacitance in the circuit if you switch from using MOSFETs to BJTs.
💡 Hint: Research the inherent differences between BJTs and MOSFETs to support your analysis.
