Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given L = 10 mH and C1 = 100 nF and C2 = 100 nF, calculate the resonant frequency f0. Below that, explain how changing the values of C2 would shift the frequency.

💡 Hint: Complete the equation in steps to find Ceq before f0.

Challenge 2 Hard

Design a complete Colpitts oscillator circuit that addresses the need for a specific output frequency of 200 kHz. Specify component values and discuss the implications of tolerances.

💡 Hint: Break down the design process using the resonant frequency formula first to establish a baseline.
