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.
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.
