Challenge Problems
Push your limits with challenges.
Question 1
A circuit engineer records the following h-parameters: h11 = 2kΞ©, h12 = 0.01, h21 = 75, h22 = 15ΞΌS. How would you evaluate the input impedance if the output were to be shorted?
π‘ Hint: Simplify using the definition of h11.
Question 2
Consider a transistor that's represented with h-parameters showing h21 = 30. If the input current is 0.5mA, calculate the expected output current.
π‘ Hint: Reflect on how current gain amplifies the input signal.
