Question

1. A Colpitts Oscillator circuit having two capacitors of 24nF and 240nF respectively are
connected in parallel with an inductor of 10mH. Determine the frequency of oscillations of the
circuit, the feedback fraction and draw the circuit.​

Answer 1

An oscillator is used to produce electronic signal with oscillating periods. Eg: Sine wave, square wave etc.. Oscillators are broadly classified into two – linear oscillators and non-linear oscillators. As the name implies, linear oscillators are used to produce linear or sinusiodal waveforms. Whereas, non-linear oscillators are used to produce non-linear (non-sinusoidal output waveforms). All types of electronic oscillators use their input voltage to control the oscillation frequency.

Answer 2

A Colpitts oscillator, invented in 1918 by American engineer Edwin H. Colpitts, is one of a number of designs for LC oscillators, electronic oscillators that use a combination of inductors and capacitors to produce an oscillation at a certain frequency
