Challenge Problems
Push your limits with challenges.
Question 1
Design a common collector amplifier with a target voltage gain of nearly 1. Calculate the necessary input and output impedance if the collector current must be 1 mA.
π‘ Hint: Think through the dependent relationships of gain, resistances, and small signal models.
Question 2
Given a source resistance of 100 kΞ© and an input capacitance of 10 pF, calculate how it affects the upper cutoff frequency if connected to a load of 50 Ξ©.
π‘ Hint: Donβt forget to include total resistance in your upper cutoff frequency calculations.
