Assertion (A): Assertion: A Clapp oscillator is more stable than a Colpitts.
Reason (R): Reason: Its extra series capacitor dominates the frequency and swamps the device capacitances.
Select the correct answer from the options below.
Answer: C
Both hold and the second is the mechanism: the transistor's junction capacitances drift with temperature and bias, but a small series capacitor with a good coefficient decides the frequency and their contribution is negligible beside it. Making the frequency depend on the most stable available component, rather than on a sum including unstable ones, is a general technique and this is its clearest application in oscillator design.
