Which of the following equation gives amplitude of oscillation in Colpitts oscillator using the describing function method? (Where Ic is the is the bias current RL is the load resistor and C1 & C2 are the upper and lower capacitance of voltage divider bias)
(a) 2ICRL/C1+C2
(b) 2ICC2/C1+C2
(c) 2ICRL C2/C1
(d) 2ICRL C2/C1+C2
I have been asked this question by my school principal while I was bunking the class.
This interesting question is from Colpitts Oscillator-2 topic in chapter Oscillators of Analog Circuits
