Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a Colpitts oscillator for a frequency of 200 MHz. Given an inductor value of 5 nH, calculate the required capacitance values C1 and C2 that produce the oscillation frequency.

💡 Hint: Remember that Ceq = (C1*C2)/(C1+C2).

Challenge 2 Hard

A mixer requires a local oscillator signal at 1.5 GHz to down-convert a received signal at 2.4 GHz. Calculate the expected output frequency and discuss what issues might arise due to potential image frequencies.

💡 Hint: Consider how other frequencies could interfere with the desired output.
