Challenge Problems
Push your limits with challenges.
Question 1
Design a Hartley oscillator circuit that oscillates at 1 MHz with an L1 of 2 mH and calculate the required C. What will be the minimum current gain h_fe if L2 is 200 µH?
💡 Hint: Solve for capacitance first, then use the ratio for gain.
Question 2
If a Hartley oscillator experiences an increase in L1 causing it to be 4 times larger than L2, how would the oscillation behavior and design change?
💡 Hint: Think about the relationship between inductance and gain, especially under design changes.
