Colpitts oscillator operating at 50 MHz has an inductor in the feedback section of value 0.10µH. then the values of the capacitors in the feedback section is: Correct Answer 100 pF, 100 pF

The equivalent value of series combination of the capacitors is given by 1/ω2L. This gives the equivalent capacitance value of 200 pF. C1C2/ (C1+C2) =200 pF. C1 and C2 values can be chosen in several ways. One of the way is C1=C2=100 pF.
