Question

The Hartley oscillator is less preferred than due to Colpitts oscillator’s performance in __________

(a) All frequency region

(b) Mid frequency region

(c) High frequency region

(d) Low frequency region

I got this question by my college professor while I was bunking the class.

My query is from Hartley Oscillator-2 topic in section Oscillators of Analog Circuits

Answer 1

The correct answer is (c) High frequency region

Easy explanation: The Hartley oscillator is less preferred than due to Colpitts oscillator’s performance in high frequency regions due to stability. Colpitt’s oscillator uses a capacitive voltage divider setup which provides better stability than an inductive voltage divider as in Hartley oscillator.
