Challenge Problems
Push your limits with challenges.
Question 1
Design a Colpitts oscillator to oscillate at a frequency of 1 MHz using an inductor of 10 µH. What values of C1 and C2 would you choose?
💡 Hint: Remember to calculate Ceq first, and then distribute it into C1 and C2 based on their ratio.
Question 2
Analyze the impact on the oscillation frequency if you doubled the value of C1 while keeping C2 constant. What would happen to f0?
💡 Hint: Consider how the frequency is affected by the equivalent capacitance.
